Yeah thats it. What was useful in there for me was the luminance and colour approach to combining using Photoshop (I have been combining in CCDstack) and also how to reduce star reflections. A bit of extra data about using CCDstack to its fullest. Also a bit of data about noise reduction in the green channel. I downloaded PixInsight trial but have yet to get the trial license. I'd like to use the colour balance using G2V stars. Have to do that one day. You can download a list of G2V stars for the Sky to make the job easier. Bob's writeup is very advanced image processing and seems to me to be cutting edge. I have been admiring his posted images for a while.
