The Celestron Skymaster 25x100 binoculars are great budget astronomy binoculars that make for an alternative to a telescope. They have a massive 25x magnification which brings you right up close to galaxies, stars and star clusters.
Views from these binoculars are akin to looking through two separate telescopes and therefore bring you super immersive and detailed views that you wouldn't get from a telescope. The large 100mm objective lenses are unheard of in binoculars and allow a ridiculous amount of light through, making them perfect for dim deep space subjects, which otherwise might be harder to see with smaller objective lenses.
This deal brings their price to the lowest they have been all year and could be a great opportunity for someone who wants to get closer views of the night sky without needing to learn about or buy a telescope. They are perfect for family and group observation sessions, as you can set them up on a tripod and have different people look through them at your selected target. If these don't entice you, we have a range of skywatching deals available on our Black Friday hub, with up-to-date prices.
Key features: 25x magnification, 100mm objective lens diameter, 3-degree field-of-view, 15mm eye relief, 9 lbs 12 oz weight.
