The holidays are so close now I can almost smell ‘em 
Today’s astronomy advent calendar image is another of ours taken this year.
Stacking images is a great way of improving the clarity of individual photos, bringing out far more detail than the individual shots alone could capture.
Day 22
Astronomy Advent Calendar 22nd December - 60 individual photos of Andromeda stacked into one image (click to enlarge) - Credit: Sky-Watching/A.Welbourn
The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years from the Earth, in the constellation Andromeda. It’s also known as Messier 31 (M31) or NGC 224.
Andromeda is the nearest spiral galaxy to the Milky Way, but is not the closest galaxy overall, that accolade goes to the Canis Major dwarf galaxy.
60 stacked images created the final result above, taken using a Sky-Watcher Explorer 200P EQ5 PRO SynScan 200mm Newtonian Reflector Telescope and an un-modified Canon EOS 550D. To compare a single photo with the stacked image above have a look here.
Yeah, we’re pretty chuffed with our first use of DeepSkyStacker
