Given that transits of Mercury are reasonably rare – it's been three years since the last one, and the next won't occur until 2032 – many observers are keen to capture the moment as a keepsake. 

Luckily, photographic equipment for astronomy has become relatively cheap and widely available and so this is pretty easy to do, particularly if you are already viewing the transit through a filtered telescope. If you capture a video of all or part of the transit then you have the added bonus of taking frames from that movie to give you a photograph, too.

Now, the 2019 Mercury Transit is under way and will end at about 1:04 p.m. EST (1804 GMT). If you have the gear, here's a step by step guide to recording that cosmic  souvenir.

You'll need: 

  • Telescope fitted with a solar filter 
  • Webcam, camera or smartphone
  •  Eyepiece adapter for camera
  •  Photo/video editing software

Editor's note: For this guide, we used a proper solar filter to safeguard our eyes. NEVER look directly at the sun through a telescope or binoculars without special solar filters. SEVERE eye damage and blindness can result. 

1) Setting up your telescope

The first thing that you should do is to get your telescope pointing towards the Sun. It is even better if your telescope is able to track the motion of the Sun as it moves across the sky.

2) Attaching your camera

Attach the eyepiece adapter to your camera, webcam or smartphone and insert it into the telescope, in place of the regular eyepiece.

3) Capturing the video

Hit record on your device. Bear in mind that the whole event will last for 5.5 hours, so make sure you have plenty of memory and a fully charged battery.

4) Editing your video

Speed up the frame rate to create a time-lapse video of the transit, lasting minutes instead of hours. Isolate individual frames for the best still images.

5) Share your work!
