This is a target that i've wanted to take for a while. It is the Blue Horsehead IC4592 a faint Mag 4 reflection nebular located in Scorpius. It's also a bit noisy as it needed more time. I wasted time taking Ha (auto settings!!) and could have used this extra time in the LRGB. I had to discard the last few subs as it was getting low on the horizon and a bit too murky. 71mm Quad APO, Atik 11000M Camera 50Min Lum, 25 ea RGB for 125 mins total. Processed in Pixinsight and PS-CC.
