Description

I keep telling myself to push out some of the edge nebula pics that I have on my hard disk, yet once I finish data on the galaxy target, I go on to process it. I will get to past images soon. 

On this image, I was happy I got the data I was after (10h L, about 5h Ha and 1.5 each on RGB).  

Hope you like this result. Clear skies!
