Description

I finally ditched Ha altogether: although the captured signal was not too faint, I found it didn't bring more value than noise, eventually.
Despite CMOS taking over CCDs, I find the latter still give great results.
Processing was performed in Pixinsight, quite straightforwardly: the only "original" part of it happens after stretching, with separate processing of the stars and the starless representations.
The stars a bit too fat to my taste; however, they do not distract the overall picture, so I left them as they are. My choice ;)
Hope you like it too.
