Caldwell 62 is a galaxy (NGC 247) in the constellation Cetus — a distant island of stars far beyond the Milky Way. It appears as number 62 in the Caldwell catalogue, Sir Patrick Moore's 1995 list of 109 bright deep-sky objects for amateur astronomers. It spans roughly 19.7 arc-minutes on the sky. At about magnitude 9.2, it shows up in a small backyard telescope.

Although it appears about 19.7′ wide on the sky, its real span is roughly 206,298 light-years — the difference is a measure of how far away it lies.

Observing Caldwell 62

Caldwell 62 lies in the constellation Cetus and is best placed in the evening sky around October. Its maximum altitude above the horizon depends on your latitude. It is best placed for observers in the southern hemisphere, and sits low for those far north. 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.
