First order of business would be to setup an autoguiding solution so you can get longer subs.
10 minutes is a good length for that chip. Too long and the small well depth mean too much bleed on bright stars. Too short and you won't get enough signal to get past noise. I'd say 10 minutes on most objects and perhaps 4 or 5 minutes on bright globs.
I get no banding at all on my 8300 chip. In fact the darks are quite flawless. Maybe something to take up with the camera manufacturer.

Hi Greg, The 30 sec images were taken because I was eager to see what I was going to get and because I had what looked like a reasonable image on the screen. I think the banding may be an aberation which may be removed by bias files but I have posted a querie on the QHY forum. Time will tell.

Thanks Chris, I didn't realise how much diference there was in putting an image together in RGB compared to an OSC camera. Nice to have the likes of Jase here to give us fools a hand.
