Image Details:

This is a late season image of the Andromeda galaxy. Svbony really likes what Im doing with Smartphone Astro and was kind enough to send me some gear to see what I could do with their stuff and my phone. The weather wasnt very cooperative but I was able to get just over an hour of data on m31 before it goes behind the mountains here in Nagano. The stars arent great due to not having a bahtinov mask for focus, but Id say not bad for limited data.
