I am halfway into a test drive of PixInsight - So far I have found it difficult to get my head around but with a bit of patience it is starting to produce the goods - at test image of M20

There are still a lot of faults with the image especially the stars need fixing and the colour noise in the fainter areas of the nebula but that is my lack of experience with the software - it's a keeper for me and I can only see things improving with age.
