Night sky August 2026: What you can see tonight

The night sky tonight and on any clear night offers an ever-changing display of fascinating objects you can see, from stars and constellations to bright planets, the moon, and sometimes special events like meteor showers.

Observing the night sky can be done with no special equipment, although a sky map can be very useful, and a good telescope or binoculars will enhance some experiences and bring some otherwise invisible objects into view.

You can also use astronomy accessories to make your observing easier, and use our Satellite Tracker page powered by N2YO.com to find out when and how to see the International Space Station and other satellites. We also have a helpful guide on how you can see and track a Starlink satellite train.

You can also capture the night sky by using any of the best cameras for astrophotography, along with a selection of the best lenses for astrophotography.

Calendar of observing highlights

Saturday, August 1 – Orientation of the Summer Triangle (evening)

The Summer Triangle, the ultimate summer asterism, takes center stage directly overhead during early August evenings. Composed of Vega (in Lyra), Deneb (in Cygnus), and Altair (in Aquila), this massive asterism dominates the midnight sky.

You don't need any equipment to fully appreciate this asterism. Step outside around 10 p.m., look straight up, and locate the brightest bluish-white star — that's Vega. Look slightly to the east for Deneb, and then further south to find Altair. Since it is a guidepost for finding other celestial objects, the Summer Triangle is an important asterism to familiarize yourself with.

To image the Summer Triangle, a wide-field DSLR/mirrorless camera mounted on a sturdy tripod will do the trick. Use a wide-angle lens (14 mm to 24 mm), dial the aperture to its widest (f/2.8 or f/4), set ISO to 1600 or 3200, and use an exposure of 15 to 20 seconds. You'll capture not just the three stars, but the dense, glowing ribbon of the Milky Way running right through the middle of the Summer Triangle.

Sunday, August 2 – Comet 10P/Tempel Reaches Perihelion (evening)

Comet 10P/Tempel reaches perihelion today, its closest point to the sun in its orbit, at a distance of 1.42 astronomical units (AU). As the sun's radiation heats the comet's icy nucleus, its outgassing will peak, making this one of the best times to observe 10P/Tempel's glowing coma.

The bright waning gibbous moon will constitute a challenge tonight. It will wash out the faint, diffuse light of the comet. Your best observing window is during the brief period of complete darkness right after evening twilight ends, just before the moon rises (roughly 9:30 p.m. to 10:30 p.m. EDT for mid-northern latitudes).

Use high contrast viewing techniques to improve your experience. These techniques include draping a dark cloth or observing hood over your head to block out ambient glare and relying on "averted vision" — looking slightly to the side of the comet rather than directly at it to engage the highly sensitive peripheral cells in your retina.

Don't expect a bright, sweeping comet tail like in the movies. In a small telescope, comet 10P will look like a faint, grayish smudge or a fuzzy, out-of-focus star. Tap your telescope tube lightly. The slight vibration will help your eye detect the faint, fuzzy patch of the comet against background stars.

If you are observing while the moon is up, physically block the moonlight. Position your telescope so that a house, garage, or large tree hides the moon from your direct line of sight. Protecting your eyes' dark adaptation is critical for spotting faint cometary fuzz.

Monday, August 3 — Comet 10P/Tempel Closest Approach to Earth (evening)

Following yesterday's perihelion, Comet 10P/Tempel makes its closest approach to Earth today, passing at a safe distance of roughly 0.40 to 0.41 AU (about 61 to 62 million kilometers).

For observers on the East Coast of North America, your best viewing opportunity is a tight window from roughly 9:45 p.m. to 10:45 p.m. EDT. This gives you about an hour before the 76% illuminated waning gibbous moon breaches the horizon. If you prefer to wait until the comet reaches its highest altitude in the southern sky (between 1 a.m. and 2 a.m. EDT) to clear horizon haze, you will be fighting significant moonlight.

To cut through that intense lunar glare during the late-night window, thread a Swan Band filter (or a standard OIII/UHC narrowband filter) onto your eyepiece. These filters isolate the specific wavelengths of light emitted by diatomic carbon in the comet's gas coma while blocking the broad-spectrum skyglow caused by the moon, significantly boosting the comet's contrast.

Capturing a comet during a gibbous moon requires a specific strategy: short exposures and aggressive stacking. Instead of long, multi-minute tracked shots that will be quickly ruined by lunar skyglow, take dozens of shorter exposures (30-to-60 seconds). Use stacking to align the frames specifically on the comet's nucleus (rather than the background stars). This technique pulls the faint data of the coma out of the background noise and helps you cleanly subtract the heavy moonlit gradient in post-processing.

Tuesday, August 4 — The Red Planet Shines (predawn)

The Red Planet shines at magnitude +1.3 in the predawn eastern sky this morning.

If you're an early riser (or if you're still up from an observation session the previous evening), look above the eastern horizon around 4 a.m.. Mars will appear as a steady, distinctly orange-red "star."

Seeing Mars through an amateur telescope might appear disappointing if you expect Hubble-like images. While Mars is our immediate planetary neighbor, it still looks relatively small in telescopes, yielding very little detail. However, under excellent atmospheric viewing and using a high magnification (200× or more), you might be able to resolve some dark surface albedo features like Syrtis Major on Mars' eastern hemisphere. Under any condition, actually seeing Mars for yourself at the eyepiece beats seeing any printed, highly detailed images provided by orbiting and professional telescopes.

To capture the distinct fiery orange hue of Mars, a standard DSLR or mirrorless camera on a simple tripod with a 50 mm to 135 mm lens is all you need; frame the planet and use a 2- to 4-second exposure at f/2.8 to preserve its rich color. While a basic light pollution filter helps if you're shooting from a suburban backyard, mounting your camera directly to a small telescope opens up advanced options: slipping a light red (No. 25) or orange (No. 21) planetary filter into your optical train will dramatically boost surface contrast, making subtle Martian albedo markings and the polar cap pop out sharply against the desert terrain.

Wednesday, August 5 — Splitting the "Double Double" (Epsilon Lyrae) (evening)

Located just a hair away from the brilliant star Vega, Epsilon Lyrae is a famous quadruple star system that serves as the ultimate test of optical quality and atmospheric stability.

To the naked eye (under dark skies), Epsilon Lyrae looks like a single star. With a pair of binoculars, it easily splits into two wide, white component stars. Under steady air, using a high-power eyepiece in a telescope with an aperture of 3 inches or greater, each of those two binocular stars splits again into two distinct pairs of stars, revealing a stunning cosmic family of four.

Splitting Epsilon Lyrae's tight pairs (separated by just 2.3 and 2.4 arcseconds) requires a telescope that is perfectly acclimated to the outdoor temperature. If your telescope has been sitting in a warm house or car, tube currents will blur the stars together. Set your telescope outside at least an hour before attempting this split to let the optics cool down.

If you intend to image this quadruple star system, you'll need a telescope with a long focal length (or a Barlow lens). Shoot it as if you were imaging a planet: shoot short 1/10th-of-a-second exposures to freeze the atmospheric shimmering so the tiny gaps between the close binary pairs can be resolved on the sensor.

Thursday, August 6 — Early Perseids Watch (evening)

While the main event for the Perseid meteor shower doesn't arrive until mid-August, Earth is already plowing deeper into the broad stream of debris left behind by Comet Swift-Tuttle. Aug. 6 is not too early to catch a sneak peek.

If you step outside during the late evening hours and find a dark patch of sky away from city lights, keep your eyes peeled toward the northeast. While the hourly rates are still low this early in the month — usually just a trickle of meteors per hour — Perseids are famous for being swift, bright, and occasionally leaving persistent glowing trains in their wake.

Leave your telescope and binoculars inside for this one; meteor watching is strictly a wide-field, naked-eye affair. Lie back in a comfortable lawn chair, let your eyes adapt to the dark for at least 20 minutes, and scan a large expanse of the sky. Early August nights are warm and comfortable, making this early-bird meteor hunting a relaxing prelude to the main celestial fireworks later in the month.

Friday, August 7 — Conjunction of the Moon and the Pleiades (predawn)

This morning offers a spectacular conjunction: The waning crescent moon passes right along the edge of the Seven Sisters, the famous Pleiades star cluster (M45) in the pre-dawn sky.

You don't need expensive astronomical equipment to enjoy this breathtaking sight; a simple pair of standard binoculars will do. The slender, earthlit crescent of the moon will sit right next to the icy blue jewel box of the Pleiades. The pairing is also easily visible to the naked eye looking east around 4 a.m..

If you are using a telescope, slip in a low-power, wide-field eyepiece to fit both the lunar limb and the brightest stars of the cluster into the same field of view. Look closely at the dark side of the moon to see if any faint cluster stars are occulted (hidden) as the moon slides past.

This is also a great opportunity for smartphone astrophotographers. Place your phone on a tripod mount. Use "Night Mode," and align your phone's lens with your binocular eyepiece (this is called "afocal imaging") to capture the pair.

If you prefer to use a DSLR camera, a 135 mm to 200 mm lens will frame this conjunction beautifully. Expose for 2 to 4 seconds at ISO 800 to capture the "Earthshine" on the dark side of the moon without completely overexposing the bright crescent, while pulling in the bright stars of M45.

Earthshine is the faint glow on the unlit portion of the moon caused by sunlight reflecting off the Earth. It is incredibly photogenic during this conjunction. To balance the massive dynamic range between the bright lunar crescent and the delicate stars of the Pleiades, take a series of bracketed exposures (ranging from 1/2 a second to 4 seconds). You can blend these later in post-processing using high-dynamic-range (HDR) techniques to create an image that matches exactly what the human eye sees.

Saturday, August 8 — Mercury in Morning Twilight (predawn)

Fresh off its early August morning elongation, Mercury continues its morning apparition low in the east-northeast sky this week. Around 5:30 a.m., roughly 30 minutes before sunrise, the swift planet climbs just high enough above the horizon to catch it before the dawn glare washes it out.

Because Mercury never strays far from the sun, extreme caution is mandatory when using binoculars or a telescope. Never point optics anywhere near the eastern horizon until you are certain the sun is still safely below the edge and pack up your gear well before first light touches the upper atmosphere to protect your eyesight.

You will need a completely unobstructed eastern horizon to pull Mercury out of the ground haze and atmospheric turbulence this morning. Look very low to the east-northeast, where Mercury appears as a bright, solitary spark against the lightening gradient of dawn. Standard 10x50 binoculars will help cut through the low-altitude muck and isolate the planet.

If you are imaging the scene with a DSLR camera on a tripod, a predawn landscape shot can be deeply rewarding. Pair Mercury with a striking low-silhouette foreground, like distant treelines or a rooftop. Use a 100 mm to 200 mm telephoto lens, set your aperture around f/4, and take a quick 1-second exposure at ISO 400 right as the morning twilight begins to bloom.

Sunday, August 9 — Mars and the Moon Conjunction (predawn)

In the early predawn hours, the waning crescent moon passes a few degrees north of Mars on the edge of the constellation Gemini.

Look toward the east-northeast horizon in the very early morning around 4 am.. You'll see a lovely, thin crescent moon acting as a perfect guidepost. Look just below and slightly to the right of the moon to spot the steady, amber-colored glow of Mars.

This is an excellent opportunity to observe Earthshine on the moon while simultaneously tracking Mars. If you use a wide-field eyepiece, you can easily fit both the lunar crescent and the distinct orange disk of Mars within the same spectacular view.

For imaging the duo, a medium telephoto lens (70 mm to 200 mm) will beautifully capture the event. Expose for 2 seconds at f/2.8 with an ISO of 800. This will capture the rich orange hue of Mars and the faint, ghostly details of the dark side of the moon illuminated by earthshine.

Monday, August 10 — The Moon at Perigee & The Crescent Earthshine (predawn)

The moon reaches perigee today at a close distance of about 225,734 miles ( 363,284 km) from Earth.

Appearing as a delicate, 8% waning crescent in the early morning sky before dawn, this "Perigee Moon" is physically at its closest point in its orbit for the month, giving its visible arc a slightly larger apparent diameter (about 32.9 arcminutes).

Looking toward the eastern horizon before sunrise, observers can enjoy a brilliant display of Earthshine—sunlight reflecting off Earth's oceans and clouds to softly illuminate the unlit dark portion of the lunar disk.

The Astrophotography Experiment (Part 1):

This morning sets up a fantastic, high-reward astrophotography project! Using a DSLR/mirrorless camera on a tripod attached to a telephoto lens or telescope, photograph the thin morning crescent at a fixed focal length (500 mm or 1000 mm) with zero cropping.

Save your camera settings and image framing—on Aug. 22, when the moon reaches its furthest point at apogee, you will shoot it again with the exact same setup. Side-by-side, the nearly 11% scale difference between perigee and apogee will visibly demonstrate the elliptical shape of our moon's orbit!

Tuesday, August 11 — Perseids "Eve" & Earthgrazers (evening)

While the absolute peak is still a day away, Earth is already plunging deep into the dense debris stream left behind by Comet Swift-Tuttle. Consider tonight Perseid "Eve"—the perfect opportunity to scout your dark-sky location, set up lawn chairs, and get your camera intervalometers dialed in.

If you head out in the mid-to-late evening, before the radiant in the constellation Perseus rises high in the northeast, keep an eye out for "earthgrazers." Because the radiant is still low on the horizon, meteors entering the Earth's atmosphere come in at a very shallow angle. These rare, dramatic meteors skim horizontally across the upper atmosphere, moving noticeably slower and leaving extraordinarily long, colorful trails across the sky.

The Perseids are famous for producing bright, fast meteors and brilliant fireballs. Best of all, the moon being a razor-thin crescent that sets very early leaves the sky perfectly dark for prime viewing.

You don't need telescopes or binoculars to observe the Perseids—they actually restrict your field of view. Find the darkest location possible, away from city lights, after 10:00 PM.

Every August, Earth plows at tremendous speed into the dusty debris trail left behind by Comet Swift-Tuttle. Because of our planet's forward motion through space, all these tiny space dust particles enter our atmosphere parallel to one another. To an observer standing on Earth, perspective makes them appear to radiate outward from one specific point in the night sky.

Because that perspective point happens to line up perfectly with the stars of the constellation Perseus, we call that point the "radiant," and it gives the Perseids their legendary name.

Spread out a blanket or reclining chair, look up from the northeast horizon and try to find the constellation Cassiopeia, which has a distinct "W" shape. The radiant is below Cassiopeia's "W." While the radiant is the point from which the meteors seem to originate, it's important not to just stare directly at it.

Meteors close to the radiant will have very short, stubby tails because they are coming almost straight at you. The longest, most spectacular, and colorful streaks will actually appear about 45 to 90 degrees away from Perseus, where they pierce the upper atmosphere sideways. The best viewing "angle" is by letting your gaze drift across the darker overhead skies (near the Summer Triangle or Ursa Major), where you will catch the real showstoppers!

Serious observers can contribute scientific data by conducting a formal meteor count. Note the time, magnitude, and whether the meteor left a persistent train (a glowing trail of ionized gas). This data helps track the density of the debris stream left behind by Comet 109P/Swift-Tuttle.

If you want to image the Perseids, use a fast wide-angle lens (f/1.4 to f/2.8) set to its widest aperture. Use an ISO of 3200 or 6400 and set your camera to continuously shoot 15-second exposures.

To create a mind-blowing Perseid composite photo, do not move your tripod or change your framing all night. Later in post-processing, use software like Starry Landscape Stacker or Photoshop to align the stars across all frames. Mask in only the frames that contain a meteor. Because all the meteors will trace back to a single point in the sky (the radiant in Perseus), your final image will beautifully showcase the cosmic geometry of the shower.

Wednesday, August 12 — Solar Eclipse (daytime)

A spectacular total solar eclipse occurs today as the moon passes perfectly between Earth and the sun. While the awe-inspiring path of totality sweeps across the Arctic, Greenland, Iceland, and Spain, observers in Western Europe and North America won't be left out of the show entirely.

If you live in the Northeast, step outside early this afternoon with your certified eclipse glasses. From roughly 12:50 p.m. to 2:40 p.m. EDT, you will witness a partial solar eclipse as the moon takes a noticeable "bite" out of the northern edge of the sun.

Safety First! If you are anywhere in the partial or total visibility zones, you must use certified ISO 12312-2 solar eclipse glasses to look at the sun. Do not rely on the ISO label printed on the glasses. Rely entirely on where you buy them. The absolute best resource is the American Astronomical Society (AAS) Solar Eclipse Task Force. The AAS meticulously vets and maintains a master list of verified manufacturers, safe importers, and reputable retail distributors. Do not simply type "solar eclipse glasses" into Amazon, eBay, or Temu and buy eclipse glasses from the first random brand that pops up. Even if a listing boasts thousands of positive reviews, inventory from unvetted third-party factories frequently gets commingled in fulfillment centers, meaning a counterfeit pair can easily slip through.

Why eyesight protection is mandatory: Staring directly at the sun without proper protection—even for a few fleeting seconds—can cause immediate, permanent, and irreversible eye damage known as solar retinopathy. The danger is completely silent because your retinas do not have any pain receptors; you can literally burn a blind spot into your central vision without feeling a thing. Do not be fooled into thinking your eyes are safe during the deep partial phases when the sky begins to darken; the sun's invisible ultraviolet and infrared rays remain concentrated enough to cook delicate eye tissue. Furthermore, never experiment with homemade filters. Everyday items like sunglasses (even if stacked), smoked glass, polarized filters, 3D glasses, photographic negatives, or space blankets do not block the dangerous wavelengths of infrared light. The singular exception for DIY viewing is an indirect method, like the classic shoebox pinhole projector. By poking a small hole in one end of a box, you let the light pass through to project a safe, miniature image of the eclipsed sun onto a white card at the opposite end—allowing you to watch the entire event with your back completely turned to the sun.

For those outside the path, live streams will be broadcast online, making this a great global event to follow from anywhere.

If you have traveled into the path of totality (especially in Iceland or Spain), prepare for the sudden drop in temperature and the appearance of the solar corona. Keep an eye out for "Baily's Beads" and the "Diamond Ring" effect in the seconds immediately before and after totality.

While the partial eclipse is a fun daytime treat, this exact celestial alignment delivers an even better gift to meteor hunters tonight: a precise New Moon. This means the night sky will be 100% devoid of moonlight. When the Perseids begin to ramp up toward their maximum rates late this evening, you will have pristine, pitch-black skies. Without any lunar glare to wash out the stars, even the faintest, thinnest meteors will be clearly visible.

Thursday, August 13 — The Perseid Meteor Shower Peak (predawn)

This is the main event. The mathematical peak of the Perseid meteor shower occurred late last night, making the dark, predawn hours of Thursday morning the absolute best viewing window of the year. Rates can soar up to 100 meteors per hour under ideal, dark country skies.

Head outside after midnight, lie back in a reclining chair or on a blanket, and let your eyes adapt to the dark for at least 20 to 30 minutes. The radiant point in Perseus will be climbing high in the northeast, but you do not need to stare directly at it — meteors will streak across the entire sky. Under tonight's perfect, moonless conditions, observers in dark locations can expect to see anywhere from 60 to 100 meteors per hour. Look for the Perseids' signature speed and the bright, glowing smoke trains they leave lingering in their wake. Put the telescopes away; this is strictly a naked-eye spectacle.

If you would like to try your hand at astrophotographic meteor hunting using two cameras, set one up facing the radiant in the northeast with a 24 mm lens to capture shorter, brighter streaks. Point the second camera roughly 90 degrees away (toward the northwest or south) with a 14 mm lens to catch the longer, dramatic trails.

Friday, August 14 — Venus in the Evening Twilight (evening)

This evening, Venus is steadily climbing out of the solar glare, shining as the brilliant "Evening Star" over the western horizon after sunset.

Venus is an easy and satisfying target this month. You can't miss her: Venus will be the brightest object in the sky, blazing at magnitude -4.1. It's so bright it will easily pierce through any local light pollution.

When viewed through a telescope, Venus appears approximately 50% illuminated. Because it sits low in the atmosphere at sunset, atmospheric dispersion will cause color fringing (red on one side, blue on the other). Use an atmospheric dispersion corrector (ADC) or a violet/blue filter to bring out subtle cloud structures in the Venusian atmosphere.

Because Venus is incredibly bright, it is a prime target for smartphone astrophotography. Simply secure your phone into a smartphone adapter attached to your telescope's eyepiece. Drop the exposure manually on your phone's camera app so Venus doesn't look like a blown-out white ball, and you'll easily capture its image.

Saturday, August 15 — Early Morning Planetary Double Feature: Mercury Conjoins Jupiter & Io Transit (predawn)

Early risers are treated to an extraordinary predawn double feature this morning, combining a tight planetary conjunction with an active Jovian dual transit.

Set an alarm for around 5 a.m. and secure a spot with an unobstructed, flat east-northeast horizon. Just before dawn twilight grows too bright, you will see a brilliant pair of steady silver sparks hanging low to the ground. Jupiter shines brightly at magnitude -1.8, with Mercury sitting right beside it at magnitude -1.2, both fitting comfortably within the same low-to-medium-power telescope eyepiece for a striking scale comparison between Jupiter's wide disk and Mercury's tiny waxing gibbous point of light.

Once you have enjoyed observing the pair, crank up the magnification on Jupiter to track a dual transit: the volcanic moon Io and its shadow crossing the planet simultaneously.

While Io's dark, high-contrast shadow stands out like a stark ink dot in almost any telescope, picking out the pale disk of Io itself as it glides over Jupiter's cloud tops requires a sharp, higher-aperture scope and steady atmospheric conditions.

If you plan to photograph the pair of planets, act quickly before sunrise washes them out. A 200 mm to 300 mm lens will frame the duo perfectly; fire off a rapid sequence of half-second exposures at ISO 400 to balance the brightening twilight with Mercury's pinpoint glow.

Above all, exercise extreme caution when using binoculars, cameras, or telescopes. Because the sun is rising directly behind this planetary lineup, never sweep the horizon once the sun breaks the skyline, as pointing optics anywhere near the rising Sun can cause instant and permanent eye damage.

Sunday, August 16 — Swimming through the Sagittarius Star Cloud (M24) (evening)

Known as the Great Sagittarius Star Cloud, Messier 24 isn't actually a single cluster; it is a massive structural "window" in the Milky Way's dust lanes, revealing a dense cluster of thousands of stars.

This is the ultimate target for a standard pair of 10x50 binoculars on a warm August night. Around 10 p.m., look toward the southern sky just above the "teapot" asterism of Sagittarius. The cloud will look like a giant, glowing thumbprint of light stretching across the starry backdrop.

For best viewing, use a wide-field, low-magnification eyepiece in a 4-inch or larger telescope. Rather than seeing individual components, you will be treated to a seemingly infinite carpet of background stars. Look closely for dark nebulas—dense pockets of interstellar dust like B92 and B93, which appear as black silhouettes directly in front of the starlight.

For wide-to-medium field imaging, a 50 mm or 135 mm lens on a small star tracker is ideal here. Expose for 90 seconds at f/2.8 and ISO 800. The sheer star density of the final stack will be breathtaking, showing complex ribbons of dark galactic dust winding through millions of background stars.

Monday, August 17 — The Sparkling Jewel of Sagittarius (M22) (evening)

Riding high in the southern sky after nightfall, the Great Sagittarius Cluster (M22) takes center stage as one of the finest, brightest globular clusters in the entire night sky.

While Messier 13 in Hercules often steals the spotlight, M22 is actually closer to Earth at roughly 10,600 light-years away, making it appear noticeably larger and brighter through amateur optics. Located just two degrees northeast of Kaus Borealis — the top star forming the lid of the famous "Teapot" asterism in Sagittarius — M22 is remarkably easy to locate even for beginners. In standard 7x50 or 10x50 binoculars, it reveals itself as a large, bright, ghostly sphere of light set against the rich, shimmering backdrop of the Milky Way.

Bringing a small-to-medium telescope to bear at 80x to 150x magnification instantly transforms that foggy patch into a sparkling jewel box, resolving dozens of individual stellar points around its outer margins. Larger instruments will expose a dense, granular core packed with hundreds of thousands of ancient, low-metallicity stars that formed in the early stages of our galaxy's history.

For astrophotographers, short exposure sequences through a fast setup will easily pull out M22's brilliant golden-red giant stars without washing out its vibrant, tightly packed center, offering a magnificent deep-sky centerpiece for a late August night.

Tuesday, August 18 — Venus and the Moon Evening Pairing (evening)

While this event is not an actual conjunction, Venus and the moon offer a gorgeous twilight spectacle this evening. Low in the western sky, the waxing crescent moon, just a few days old, keeps company to dazzling Venus.

Look over the western horizon roughly 45 minutes after sunset — you won't be able to miss this pair! Venus will be blazing like a beacon, accompanied by a beautiful crescent moon. It is a textbook naked-eye photo opportunity.

Point a telescope at the young moon during this planetary encounter. The low angle of sunlight hitting the lunar landscape highlights the rugged eastern rim of the moon, throwing dramatic details across the floor of the Mare Crisium basin.

This is the perfect event for a beautiful landscape composition. Use a 50 mm to 100 mm lens on a tripod and lock focus directly onto Venus. Expose for 1 to 2 seconds at f/4, keeping the ISO low (around 200 or 400) to capture the beautiful orange and blue gradient of the evening twilight sky.

Wednesday, August 19 — Saturn's Moon Parade (predawn)

Riding high in the south-southeast around the predawn hours, Saturn offers backyard observers one of the most mesmerizing sightlines of the year—a dramatic "Moon Parade" set against the planet's unusually narrow, shallowly tilted ring system.

Because Saturn's rings are open to an angle of only roughly 7.5 degrees relative to Earth, its major icy satellites line up in a crisp, nearly straight plane extending outward from the planet's equator, mimicking a miniature solar system in the eyepiece.

For beginning stargazers equipped with a small telescope (such as a 60 mm to 80 mm refractor or a small reflector), the undisputed star of the show is Titan. Shining brightly at magnitude +8.4, Saturn's massive, smog-shrouded moon is easily spotted even from light-polluted suburban backyards, sitting well off to the side of the ring plane.

With a modest step up in aperture to a 4-inch or 6-inch telescope, three additional inner moons drop into visual range: Rhea (magnitude +9.7), Tethys (magnitude +10.2), and Dione (magnitude +10.4).

Observers using larger instruments—such as an 8-inch to 10-inch Schmidt-Cassegrain—can push further to snag the two-faced moon Iapetus lurking further out in its orbit, as well as the elusive, ocean-bearing world Enceladus (magnitude +11.7), which sits tantalizingly close to the glare of Saturn's outer ring tips.

To make the most of this celestial family portrait, use medium-to-high magnification (120x to 200x) during a moment of steady atmospheric seeing, and give your eyes five minutes at the eyepiece to allow faint pinpoint sparks to resolve alongside the pale, straw-colored globe of Saturn itself.

Thursday, August 20 — Magnificent Crater Theophilus (evening)

With the moon roughly 56% illuminated tonight, the sunrise terminator line casts long, dramatic shadows across the lunar highlands.

While the 310-mile (500 km) cliff face of Rupes Altai winds through the southern landscape nearby, the absolute star of the night is the magnificent crater Theophilus. Measuring 100 kilometers across, Theophilus sits prominently along the northwestern edge of Mare Nectaris, resting right against its neighbor Cyrillus.

In a small telescope or high-power binoculars at 80x to 150x magnification, Theophilus delivers stunning 3D relief thanks to its sharp, heavily terraced outer walls and a massive, multi-pointed central peak rising nearly 1.4 km above its sunken floor.

The low evening sunlight catches these central peaks, making them glow brightly like tiny islands of light against the deep shadows filling the crater interior.

To capture this region with a planetary camera, use a red or infrared-pass filter to stabilize atmospheric seeing, recording a 3,000-frame video sequence focused directly on Theophilus and the Nectaris Basin to stack and reveal intricate ridge details along the terminator.

Friday, August 21 — Locating the Ring Nebula (M57) (evening)

The showpiece of the constellation Lyra, the Ring Nebula, is the glowing, ghostly remnant of a dying sun-like star that puffed away its outer atmosphere into deep space thousands of years ago.

While you cannot see the ring structure without a telescope, you can easily find its cosmic home. Look straight up after dark to locate the brilliant star Vega. Just below it is a neat little parallelogram of stars that makes up the "body" of Lyra; M57 sits almost exactly halfway between the two bottom stars of that shape: Sulafat and Sheliak.

If you point a 4-inch or larger telescope at M57 using a high-power eyepiece (100x to 150x), the nebula will pop into view as a small, pale gray, ghostly smoke ring floating silently against the dark background stars. If you want to see more details, thread an oxygen-III (OIII) or a narrowband nebula filter into your eyepiece to boost the contrast and reveal the darker center of the ring.

M57 is a good target for budding astrophotographers. It is small but it has high surface brightness. Image it using a telescope with a focal length of 600 mm to 1000 mm on a tracking mount. Shoot a sequence of 2-minute exposures at ISO 1600. In the final stacked image, the pale gray ring will transform into a brilliant cosmic target, showing off a deep blue interior surrounded by a glowing red outer ring of hydrogen gas.

When visually observing faint planetary nebulae like the Ring Nebula, the central star (which shines at a very faint 15th magnitude) is incredibly elusive. To trick your eyes into seeing finer details within the ring itself, use a technique called "averted vision." Instead of staring directly at the nebula, look slightly to the side of it in the eyepiece. This projects the light onto the more light-sensitive rod cells on the outer edges of your retina, making the faint outer halo of the ring instantly appear brighter.

Saturday, August 22 — The apogee moon & Mare Imbrium high sun (evening)

The Moon reaches apogee today—its farthest point from Earth this month at roughly 404,642 km away. Sitting at a 75% waxing gibbous phase in the evening sky, this "Micro-Moon" appears roughly 11% smaller in apparent diameter and slightly fainter than it did during perigee on August 10th.

Visually through a small telescope, high solar illumination is sweeping over Mare Imbrium, causing the intense, brilliant white ray systems radiating from crater Copernicus to blaze vividly against the dark, surrounding basaltic plains.

The Photography Experiment (Part 2):

Tonight is the payoff for your August 10th setup! Photograph the waxing gibbous Moon tonight using the exact same camera, telescope focal length, and framing parameters you used for the morning crescent on the 10th.

When you composite or place tonight's Apogee image side-by-side with your August 10th Perigee photo, the difference in size will be strikingly obvious—a textbook demonstration of orbital dynamics.

Sunday, August 23 — Splitting Albireo (Beta Cygni) (evening)

The beautiful double star Albireo marks the head of the Swan, the constellation Cygnus. To the naked eye, it appears as a single, modest 3rd-magnitude star, but it hides the most beautifully colored double-star system in the entire night sky.

On a clear summer night, this is the absolute best first double star for amateurs starting out with a small telescope or basic 10x50 binoculars. Even with minimal magnification, Albireo splits into two distinct stars sitting close together. The color contrast is magnificent: one star glows a rich, warm amber-gold, while its companion shines a brilliant, icy sapphire-blue.

To image the vivid, contrasting colors of Albireo on a camera sensor without blowing out the highlights, use a modest focal length (500mm or above) and deliberately slightly de-focus the stars just a hair. This spreads the light across more pixels, preventing sensor saturation and revealing the pure, deep blue and gold hues in your final image.

Monday, August 24 — Vesta and Pallas in Cetus (predawn)

If you are looking for a unique predawn challenge this morning, grab your observing gear and look toward the constellation Cetus in the southern sky around 4 a.m.. Two of the largest bodies in the asteroid belt, Vesta and Pallas, are currently drifting through this region. Vesta is approaching its autumn opposition and glows at a respectable magnitude 7.4. Meanwhile, Pallas is slightly fainter at magnitude 8.9 as it heads toward its own opposition in early October. With the moon safely out of the sky by this hour, you will have the beautifully dark conditions necessary to hunt down these ancient protoplanets.

At magnitude 7.4, Vesta is an accessible target for standard 7x50 or 10x50 binoculars. It will appear as a distinct, faint point of light. Mounting your binoculars on a tripod is highly recommended to keep the star field steady while you scan.

Star-Hopping with a Telescope: Because Pallas requires a bit more aperture, a moderate telescope is the best tool for the job. If you are not using a computerized GoTo mount to do the heavy lifting, the key to finding both asteroids is careful star-hopping. Start with a wide-field, low-power eyepiece (around 25 mm to 32 mm) to match the view in your star chart or astronomy app. Find a bright anchor star in Cetus, such as Deneb Kaitos, and slowly work your way to the target coordinates.

Once you have pinpointed the correct star field, bump your magnification up to between 75x and 100x. This moderate power darkens the background sky, increasing the visual contrast and making these magnitude 7 and 8 targets pop against the blackness of space.

Confirming the Catch: Because asteroids look exactly like faint background stars (the word asteroid literally means "star-like"), you will not see a planetary disc. To confirm you have actually spotted Vesta or Pallas, make a quick pencil sketch of the star field in your eyepiece—or take a simple, short-exposure wide-field photograph. Return to the exact same spot a night or two later and compare the view. The "star" that has moved against the stationary background is your minor planet!

Tuesday, August 25 — Deep-Sky Showcase — The Hyades (predawn)

If you want a spectacular and often overlooked deep-sky target, turn your gaze high into the eastern pre-dawn sky to spot the distinctive V-shape of the Hyades star cluster. Marking the face of Taurus (the Bull), the Hyades is the closest open star cluster to our solar system, sitting just 153 light-years away. Because it is so close, it appears incredibly large in the sky, stretching across over five degrees. You will easily spot the brilliant orange-red star Aldebaran anchoring one tip of the "V." While Aldebaran looks like the brightest member of the cluster, it is actually a cosmic optical illusion — Aldebaran is a foreground star less than half as far away, simply photobombing our view of the true cluster behind it!

Put the telescope away for this one. Because the Hyades is so massive, it will overflow the field of view of almost any telescope. This is strictly a naked-eye and binocular target. Once the bright moon sets around 3 a.m., grab a comfortable lawn chair and a pair of 10x50 binoculars to take in the sprawling, glittering field of stars.

The Hyades is a fantastic wide-field astrophotography target. Using a standard 50 mm to 85 mm portrait lens on your DSLR, you can capture the entire "V" shape and the striking color contrast between the fiery orange of Aldebaran and the cooler white and blue stars of the cluster. A tracking mount with short 30-second exposures will yield a stunning, crisp star field.

Wednesday, August 26 — Kickoff of "Saturn Prime" Observing Season (all night)

As August winds down, the ringed jewel of the solar system, Saturn, begins rising in the east-southeast, marking the official kickoff of the prime Saturn observing season. While Saturn spent the earlier summer months strictly as a predawn target, it is now rising early enough to make late-evening viewing convenient. By 10 p.m., Saturn climbs high enough in the southeast sky to escape the turbulent ground fog, shining with a steady, yellowish-white light at a bright magnitude of +0.3. A telescope of any size will reveal the iconic rings, which will instantly take your breath away.

Saturn's rings are currently tilted at a narrow angle of approximately -7.5 degrees, meaning we are looking at them nearly edge-on. This shallow inclination is perfect for hunting Saturn's fainter, smaller moons (like Tethys, Dione, and Rhea) that are normally drowned out by the bright glare of widely open rings, while Titan glows like a tiny golden star nearby. Look closely for the delicate, dark line of the Cassini Division breaking up the ring structures.

For high-focal-length planetary imaging, fire up your longest Schmidt-Cassegrain setup (like a C8) paired with a 2x or 3x Barlow lens to stretch your focal length. Keep your exposure times short (under 1/30th of a second) to combat atmospheric dancing, and apply a gentle unsharp mask in post-processing to snap the razor-thin rings into sharp relief against the planetary globe. Because Saturn rises roughly four minutes earlier each night as Earth catches up to it in orbit, these late-evening viewing hours will only get better and earlier throughout September, leading up to its peak opposition in October.

Thursday, August 27 — Partial Lunar Eclipse (evening)

A spectacular, ultra-deep partial lunar eclipse takes place tonight, with a staggering 96.2% of the Full Sturgeon Moon plunging into the dark center of Earth's umbral shadow.

Because nearly the entire disk enters the shadow, this event will visually mimic a Total Lunar Eclipse, causing the moon to drastically dim and take on a gorgeous copper-red or deep orange hue.

The Americas offer the absolute best seats in the house, with the entire five-hour event playing out high in the sky from start to finish. In Eastern Daylight Time, the subtle penumbral shading begins tonight at 9:24 p.m. EDT, followed by the dark umbral bite taking over as the partial phase begins at 10:34 p.m. EDT.

Maximum eclipse hits just after midnight at 12:12 a.m. EDT on the morning of August 28th, with the dark shadow retreating until the partial phase ends at 1:52 a.m. EDT and the penumbral phase concludes at 3:01 a.m. EDT.

For observers in Europe and Western Africa, the eclipse will be visible low in the western sky during the pre-dawn hours of Aug. 28, with the moon setting right as maximum phase hits. Unlike solar eclipses, lunar eclipses are completely safe to watch with the naked eye, requiring no special filters. Because 3.8% of the moon's northernmost rim remains outside the darkest umbral shadow, the moon will display a striking high-contrast visual gradient: a brilliant, dazzling white sliver on the top edge fading into a deep, moody blood-orange tone across the rest of the lunar landscape.

For astrophotographers, maximum eclipse presents the ultimate HDR challenge. To capture both the bright un-eclipsed white rim and the faint red details of the shadowed portion, shoot an exposure bracket using short exposures around 1/250th of a second for the rim and longer exposures of two to four seconds at ISO 800 for the copper tones.

As a bonus, because the Moon dims so drastically during peak eclipse, the surrounding night sky will temporarily turn pitch-black, causing faint background stars to pop into view and offering a rare chance to capture deep Milky Way compositions with a dark red moon embedded right among the stars.

Friday, August 28 — Lunar Spotlight: The Dark Floor of Crater Plato (evening)

With the moon still glowing at 99% illumination following last night's eclipse, deep-sky hunting is off the table. Instead, point your telescope toward the moon's northern hemisphere to observe one of its most striking high-contrast features: the crater Plato. Often referred to by early astronomers as the "Great Black Lake," Plato is a massive, 100-kilometer-wide impact crater located just north of the vast Mare Imbrium (Sea of Showers).

Billions of years ago, the original crater floor was completely flooded by dark, iron-rich basaltic lava. Tonight, with the Sun beating straight down on the lunar surface, that dark volcanic rock creates a stark, beautiful contrast against the blindingly bright, rugged terrain of the surrounding Montes Alpes (lunar Alps).

Observing a nearly full moon through a telescope is like staring into a flashlight. Thread a neutral density filter (or a polarizing moon filter) onto your eyepiece to cut the painful glare and increase the contrast. Once you locate Plato's dark oval, bump your magnification up to 150x or 200x. If the atmospheric seeing is exceptionally steady, try to spot the tiny, elusive "craterlets" scattered across Plato's dark floor—a classic optical test for amateur astronomers.

You don't need a dedicated planetary camera to capture this. If you have a smartphone adapter mount for your telescope eyepiece, you can easily snap a great photo. The key is to manually lower your phone's exposure slider to prevent the bright lunar highlands from blowing out into pure white, allowing the dark floor of Plato to remain a deep, moody gray.

Saturday, August 29 — Hunting the Dumbbell Nebula (M27) (evening)

Keeping the Fox (the small constellation of Vulpecula) company, the Dumbbell Nebula (M27) holds a special place in history as the very first planetary nebula ever discovered. Shining at a bright magnitude of 7.09, it is one of the largest and most impressive expanding stellar shrouds in the sky.

Normally, M27 is easily swept up in standard binoculars, but with a brilliant 98% illuminated Moon dominating the sky tonight, you will need a telescope to cut through the lunar glare. Look roughly halfway between the distinct shape of Sagitta (the Arrow) and the bright star Albireo.

Using a low-to-medium power eyepiece with a 6-inch diameter or larger telescope, the nebula's famous namesake shape will pop into view—a clear, double-lobed, hourglass or "dumbbell" structure of glowing gas.

Tonight is the perfect night to thread an OIII (Oxygen-III) or light-pollution filter onto your eyepiece. These filters block out the moonlight while letting the nebula's specific light pass through, revealing the outer, fainter "wings" of the expanding gas envelope.

M27 has excellent surface brightness for a deep-sky close-up, making it a highly rewarding target for suburban astrophotographers. Use a focal length of 500 mm or longer on a tracking mount. If you are using a dual-band narrowband filter to combat the moonlight, shoot a series of 2-minute exposures. The final image will showcase a striking cosmic display: a brilliant apple-green core of ionized oxygen flanked by deep, glowing red wings of hydrogen gas.

Sunday, August 30 — The Moon and Saturn (evening)

Tonight, fresh off its dramatic eclipse, the waning gibbous moon pairs up beautifully with the ringed planet Saturn in the constellation Pisces.

Look toward the southeast sky around 10 p.m.. The moon will still be bright and heavy, but right next to it — separated by just a few degrees — will be a bright, steady, pale yellow star. That "star" is Saturn. The duo makes for an easy and compelling visual pair for binoculars.

This conjunction provides a great opportunity to compare the color tone of the lunar surface with the distinct cloud atmosphere of Saturn. Use a wide-field telescope eyepiece to see if you can track both the brilliant craters on the lunar terminator and the steady, edge-on ring system of Saturn without needing to adjust your mount.

If you would like to image this planetary encounter, a 200 mm to 300 mm telephoto lens on a steady tripod can easily fit both bodies into the frame. Because the Moon is incredibly bright compared to Saturn, turn down your exposure settings to ensure the lunar details aren't overexposed, and let Saturn sit as a sharp, elegant golden pinprick right beside it.

Monday, August 31 — Tracking the Garnet Star (Mu Cephei) (evening)

To close out the month, we target one of the largest and most intensely colored stars visible to the human eye: Mu Cephei, famously nicknamed the "Garnet Star" by Sir William Herschel due to its deep, striking color.

Located in the house-shaped constellation of Cepheus high in the northern sky, this star normally shines at magnitude 4.1. With a bright waning gibbous moon rising by mid-evening tonight, you might struggle to spot it with the naked eye, but through binoculars, its incredible color punches through: it glows with a deep, unmistakable, dark reddish-orange hue, looking like a burning cosmic ember.

Mu Cephei is a colossal red supergiant — if it were placed in the center of our solar system, its outer surface would extend all the way past the orbit of Jupiter. It is also a semi-regular variable star, fluctuating in brightness over hundreds of days. Track its brightness throughout the coming autumn months against nearby stable background stars to map its stellar pulse.

Photograph Mu Cephei using a medium telephoto lens (100 mm to 200 mm). The deep, garnet-red color of the star creates a beautiful, eye-catching contrast against the icy white and blue stellar background of the surrounding Milky Way star fields, making it a perfect, poetic final image for the August calendar.

Skywatching terms

Gibbous: Used to describe a planet or moon that is more than 50% illuminated.

Asterism: A noteworthy or striking pattern of stars within a larger constellation.

Degrees (measuring the sky): The sky is 360 degrees all the way around, which means roughly 180 degrees from horizon to horizon. It's easy to measure distances between objects: Your fist on an outstretched arm covers about 10 degrees of sky, while a finger covers about one degree.

Visual Magnitude: This is the astronomer's scale for measuring the brightness of objects in the sky. The dimmest object visible in the night sky under perfectly dark conditions is about magnitude 6.5. Brighter stars are magnitude 2 or 1. The brightest objects get negative numbers. Venus can be as bright as magnitude -4.9. The full moon is -12.7 and the sun is -26.8.

Terminator: The boundary on the moon between sunlight and shadow.

Zenith: The point in the sky directly overhead.

Night sky observing tips

Adjust to the dark: If you wish to observe fainter objects, such as meteors, dim stars, nebulas, and galaxies, give your eyes at least 15 minutes to adjust to the darkness. Avoid looking at your phone's bright screen by keeping it tucked away. If you must use it, set the brightness to minimum — or cover it with clingy red film.

Light Pollution: Even from a big city, one can see the moon, a handful of bright stars, and the brightest planets — if they are above the horizon. But to fully enjoy the heavens — especially a meteor shower, the fainter constellations, or to see the amazing swath across the sky that is the disk of our home galaxy, the Milky Way — rural areas are best for night sky viewing. If you're stuck in a city or suburban area, use a tree or dark building to block ambient light (or moonlight) and help reveal fainter sky objects. If you're in the suburbs, simply turning off outdoor lights can help.

Prepare for skywatching: If you plan to be outside for more than a few minutes, and it's not a warm summer evening, dress more warmly than you think is necessary. An hour of winter observing can chill you to the bone. For meteor showers, a blanket or a lounge chair will prove to be much more comfortable than standing or sitting in a chair and craning your neck to see overhead.

Daytime skywatching: On the days surrounding the first quarter, the moon is visible in the afternoon daytime sky. At last quarter, the moon rises before sunrise and lingers in the morning sky. When Venus is at a significant angle away from the sun, it can often be spotted during the day as a brilliant point of light — but you'll need to consult an astronomy app to know when and where to look for it. When large sunspots develop on the sun, they can be seen without a telescope — as long as you use proper solar filters, such as eclipse glasses. Permanent eye damage can occur if you look at the sun for any length of time without protective eyewear.
