NGC 7009: The Saturn Nebula

The Saturn Nebula, also known as Caldwell 55, is a planetary nebula viewable in the northern night sky in autumn in constellation Aquarius. Even though dim nebulas like NGC 7009 can be challenging to view in suburban backyards because of light pollution, astronomers should not loose heart. This nebula is pretty easy to spot on a moonless night with a smaller telescope. It will appear light-blue or green and as a small smudge in the scope.
