The Andromeda Galaxy, Messier 31, is the largest of the galaxies in our Local Group of galaxies. The Milky Way Galaxy, our own, is the second largest. Just as we have the Greater and Lesser Magellanic Clouds as satellite galaxies, M31 has M32 and M110 along with perhaps a dozen others as its satellites.
Below is a composite image of M31 and its two largest satellites. M32 appears in the middle-left of the image as a spherical glob. M110 appears in the lower right-hand portion of the frame as a small disc. This image is a stack of 153, 60-90 second frames taken with the backyard 130mm astrograph fitted with a light pollution filter. The total exposure time is 3h6m. The color correction is poor (mea culpa), and the galaxy center is a bit blown out, but it’s a start. I need more data and much more photo processing practice to do it justice.
