The Andromeda Galaxy (M31)
This is my first Andromeda Galaxy image of the season and is composed of images gleaned from 3 separate nights.
On the first night the clouds did not clear until 2 am; on the second the wind was too high and with gusts all night; on the third night we battled with heavy dew almost immediately and finally fog. From what should have been 9 fabulous hours of great imaging I only managed to salvage 44 shots totalling 2 hours of integration to produce the image above.
