My best Andromeda galaxy image so far. It is only 30 minutes of total exposure but autoguiding makes a huge difference by making all the details clear and sharp. Have to collect more data on the next clear night.

The Andromeda Galaxy, also known as Messier 31 (M31) is a barred spiral galaxy approximately 2.5 million light-years from Earth and the nearest major galaxy to the Milky Way. It is larger than Milky Way galaxy by about 25-50%. Two other galaxies are in this view - M32 (above M31) which is a satellite galaxy of M31 and M110 (bottom of frame) which is also part of the Andromeda group of galaxies.
