The best telescope for viewing galaxies is a large-aperture Dobsonian reflector, and if you can carry 8 inches or more you will see real structure in targets like Andromeda, the Whirlpool Galaxy and Bode’s Galaxy rather than a grey smudge. Our roundup covers seven scopes from 130mm tabletop Dobs to an 8-inch GoTo Schmidt-Cassegrain, tested … Read more
If you have been wondering whether a telescope is worth buying under a bright orange sky, the short answer is yes, with one honest qualification.
