M31 / NGC224
"Andromeda Galaxy"

M31 is one of the largest and brightest non-stellar objects in the sky. This image covers a rectangle of sky approximately 6x4 degrees. The full moon is one half degree in diameter. Two satellite galaxies, M32 and M110, are easily visible in a small telescope. Note that all Messier catalog objects (M1 through M110) are also cataloged in the New General Catalog (NGC). M32 is the same object as NGC221 and M110 is the same object as NGC205.

Two other galaxies are also associated gravitationally with M31. NGC185 and NGC147 are technically in constellation Cassiopia and much smaller than M31. NGC147 is about 1.5 degrees west of NGC185 and is slightly dimmer and more diffuse. Both appear as clouds without nuclei. They are difficult in an 8" or smaller telescope, especially in light polluted skies.
