Melotte 15 (Heart of the Heart) HaRGB - 4 Dec 2019

About this image

I started to capture this in Sept 2019 with some test shots in Ha which worked well and has been previously posted, so I returned to it during Nov-Dec 2019, to add RGB data and more, longer exposure Ha. I also shot some L data, but found it difficult to blend with the Ha, so left it out. The Ha stars overwhelmed the RGB stars, so I shot some 2min RGB subs for star colour and layered that in PS.
