For the very best views of the night sky
Written by Stuart Atkinson and Nigel Watson
et Andromeda in your sights
Make sure you're equipped for the very best views of our nearest spiral, also known as Messier 31
You’ll need: ✔A dark observing site ✔ Our finder charts ✔A pair of binoculars (optional) ✔A small telescope (optional)
1
Get dark adapted
It’s important to let your eyes adapt properly. Messier 31’s light is spread over a wide area and any light pollution or moonlight will hide it from view.
2
Find Cassiopeia
First find Cassiopeia, a W-shaped constellation high in the Northern Hemisphere sky. Then locate the upside-down ‘Y’ of Perseus directly by it.
3
Use star hopping
Starting at Mirfak, the central star in Perseus, slowly ‘star hop’ two stars along to the right to Mirach in Andromeda.
4
Seek a smudge
Look for an elongated smudge of light a short distance from Mirach. This is Messier 31. Use averted vision if you don’t see it right away.
5
Use binoculars
Use binoculars if you can’t see Messier 31 with just your eyes. You will see it as a distinct ovalshaped blur that’s grey-white in colour.
