ollypenrice Posted September 7, 2016 Share Posted September 7, 2016 (edited) (I'm simply cribbing the catalogue number from an excellent Thomas Henne APOD submission, by the way.) OK, so with 24 hours of HaLRGB, here's the two panel. Having got the feel of the data in the first go (top frame of this) I took a different approach this time. The star control is tight which means this is intended to be presented in fairly small format rather than be zoomed in on. Keeping the stars down is vital in small formats, I think. The full version on my gallery site is half size. The Ha signal is plentiful but I applied it sparingly to try and keep that eerie look it has and I applied it to red and, sparingly, blue in order to keep the colour very close the nebulosity showing in the RGB. This was distinctly magenta and similar to what you see here.
