Hi Paul,
I had taken some shots of The Leo Triplet earlier this year and I noticed a small area of amp glow in one corner. I closer look of other shots also showed it. I have read that the QHY8L does have a small amount of amp glow.
I keep my processing simple. I use Deep Sky Stacker. I just click on my lights, darks and flats and it does it all automaticaly. Maybe it's not as good as more advanced programs, but I have been happy with the results.
Ross.
