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.
