Thanks for the interest Ray.
With APP I have only started to scratch the surface. The light gradient removal process seems to have a big impact on the final result. For APP light pollution and star colour correction see
Part 3
Attached is the outcome from another attempt at processing the stack. What is encouraging is that the 2 brightest stars are showing accurate colour as described in the star catalogues.
There is still a way to go with this yet as this is my first exposure to lens (as opposed to scope) data. I am trying to produce accurate colour influenced by
Roger Clark , see his section 2 articles. I looked on Astrobin for NGC7000 but it looks like anything goes, so I am still searching for what is accurate colour for NGC7000.
As for Pixinsight, there is a guy at the local astro club who uses it. He has 10 years experience and is trying to answer questions that I haven't yet thought to ask. With imaging I think it is a progressive hobby; trying to use tools that are too complex for my skill level would be a negative thing. APP gives me more than I need (for now).
As for my lunar images, I think these are my best 2 to date

The high quality data that I am now getting from Roboscopes will mean I will be on a big learning curve with processing as there are now no excuses.
