Mesier 31, largest member of our local group of galaxies, is located in the constellation Andromeda at a distance of about 2.5 million light-years from Earth. The two satellite galaxies are M32 and (lower) M110. For this picture I have just completely reprocessed my 7 years old data (acquired with a small refractor and DSLR) to get (hopefully) better result.
