Description

My first HaRGB image. I merged(inspired from HDR processing) 4 luminance layers to not get the nuclueus of m63 too much saturated. then I added the luminance layer of the last year session I did with my previous camera asi 174MM-cooled. To get more details I added a fraction of the H alpha layer in the luminance layer. The Red channel was a merge of red + Halpha layers.
