Description

I have not really attempted any hydrogen alpha, narrowband imaging before, but I am really pleased with this. I took 20 subs at 10 minutes long each, at 7nm. Somewhere along the line I hope to get the OIII data and try my first ever bi-colour image. I took this using my Atik 460EX mono with my Skywatcher refractor 3 inch triplet. It was processed using PixInsight.
