Although it appears about 9.3′ wide on the sky, its real span is roughly 103,107 light-years — the difference is a measure of how far away it lies.
Observing Caldwell 30
Caldwell 30 lies in the constellation Pegasus and is best placed in the evening sky around August. Its maximum altitude above the horizon depends on your latitude. It is best placed for observers in the northern hemisphere, and sits low for those far south. A small backyard telescope will show it; binoculars may hint at it under dark skies. Note that the listed magnitude is spread across the whole object — diffuse galaxies and nebulae are often harder to see than the number alone suggests, so dark, moonless skies help a great deal.
