Andromeda Galaxy – M31

The Andromeda Galaxy is the nearest Galaxy to our Milky Way Galaxy, being a part of the local group. With a speed of 110..140 km/s it is approaching our Galaxy, and is one of the rare galaxies at which a blue shifted spectrum can be observed. It contains one trillion stars (10^12) whereas the Milky way contains “only” 200…400 billion stars.

This picture is taken at a starparty organised by “Sterrenwacht Rijswijk” with a very small telescope (65 mm f/6.5 and a cooled QSI wsg583 camera. Due to the moist conditions in Grandpre in september 2012, the CCD temperature was limited to 0 degrees centigrade.
