The Andromeda Galaxy (M31 - NGC 224)

The Andromeda Galaxy (M31 or NGC 224) will always fascinate me with its small elliptical galaxy M110. Its low light makes it difficult to find in the sky with a camera with little eyepice. With binoculars, you can see a white spot and that's it. In truly dark skies, it's always impressive to see a galaxy 2.55 million light-years from Earth. It’s crazy to think it has about a trillion stars and that in several billion years it will collide with our own galaxy to form a new galaxy.

This image was captured with a Nikon D750 DSLR + Nikon AF-S 70-200 F2.8 telephoto lens + x1.4 teleconverter. I did 15 30-second poses. I added a Rollei Askroklar filter for light pollution (confined to my home near a city). The mount is the famous Skywatcher Star Adventurer Pro. Image captured in Val de Briey (France) in a -5°C night (too cold!).
