My very first CCD bicolour (even colour) image. This is not easy .. at all. I have to say that my respect for those that make this look so easy has only increased dramatically.

I was not liking how the Ha, OIII, OIII rendition had been turning out, so I decided to play a little by creating a synthetic green out of the Ha and OIII wavelengths.

Colour blending:

R: 10% Ha + 40% Sg
G: 100% OIII + 20% Sg
B: 100% OIII

I still have so much to learn especially with a tool as powerful as PixInsight.
