Frequently asked questions

Can I see it with the naked eye?

The brightest Messier objects, such as the Pleiades and the Orion Nebula, show to the eye under a dark sky. Most others need binoculars or a small telescope, and all of them look best far from city lights.

Why does it look grey and not colourful like the photo?

The eye’s colour cells do not work in dim light, so faint objects look grey. Photos collect light for minutes or hours and show colours the eye cannot see.

When is the best time to look?

When the object is high in a dark sky and the Moon is down or a thin crescent. The page gives the best time for the night you choose.
