Thanks Ross and Rick - I prefer the Ha images too. In fact the Synthetic RGBs didn't turn out as impressively as I had hoped/planned...c'est la vie!
I also had a few tracking issues with this set as I was trying to push exposures of 20mins for each exposure resulting in me using data which I might normally haven't!
RGB's were mapped as either R:Ha, G:OIII blue channel, B: OIII green channel (M8 and M16 images) or R:Ha, G:OIII green ch, B:OIII blue+20% Ha (IC4628 image)
I think I'll go back to blending small amounts of NB data with a straight RGB image and using Ha as a Lum layer in future.
Cheers
Doug
