Andromeda

A new try on a DSO. This time our neighbor Andromeda. This spiral galaxy is located at approximately 2.5 million light-years in the Andromeda constellation. Also known as M31 (Messier 31) will collide with our galaxy, the Milky Way in about 3500 million years.

I'm happy with the picture taking into account the conditions it was taken. The azimutal engine of my tracking scope was broken so I had to take 160 images of 1 second exposure (ISO 3200 thus the noise) with no tracking, 20 darks and 20 bias. I wasn't counting with getting any result and amazingly not only is possible to see the dust lanes, it is also possible to see the satellite galaxies M32 (above the main galaxy) and M110 (bottom right).

Hope you like it!
