Hello everyone,
M31 was one of the first targets that I imaged and was proud enough to share. A little over a year later I've decided to give it another go with some of the new equipment I've acquired. This really is just the combination of all my subs from several different filter setups. Of course night conditions are still not optimal with plenty of humidity and moonlight pollution. Hope you enjoy!
