Description

HaRGB combination with L-Ultimate and L-Quad Enhance.
Was a bit trickier than I would imagine to combine the different channels and layering the Ha-data but I feel like the image turned out great.
Extracted the Ha data with PixelMath from the L-Ultimate image, clipped the background and then added it as a mask to the R-channel on the RGB image. 
Personal choice of me not wanting the reds on the background, going for a more subtle look. Might go back at a later time to add more data, maybe I've changed my mind by then and go for a crazier look.
Such a mindblowing thing to think about, imaging nebulae in a galaxy 2.5 million light years away. 

Taken during two cold nights in Sweden with temperatures down to -15 degrees.
