Galaxy M31 in Andromeda

I took this photo in the village during winter. The temperature was -31 degrees Celsius. There was no other option — if it were warmer, there would definitely be clouds. I warmed up in my parents' small house. The power bank lasted for about 100 photos, then I had to swap it and warm up by the stove. The shooting lasted about 2.5 hours, with each frame using in-camera noise reduction. Aiming the Nexstar in such cold was quite a hassle.
