This is an attempt to combine RGB and NB data. The image consists of 30 x 120s of Ha and OIII plus 10 x 120s of R, G and B taken with a ZWO-ASI1600 + Canon 200mm. Image acquisition was all done using an ASIair controlled from an iPad.

Pre-processing was completed in APP. PI was used for background extraction. Non-linear Ha and OIII were combined in PixelMath R:G:B - Ha : 0.3*Ha+0.7*OIII : OIII). Linear RGB were combined in ChannelCombination and then stretched using ArcsinhStretch. The two images were then combined in Photoshop and tweaked with Levels and a little noise reduction. I am sure it must be possible to get more star colour.

I find it really hard to combine RGB and NB so any critical/helpful comment or advice would be most welcome.
