One recurring feature I have noticed in your images is the absence of noise. I'm very interested to see what, if any, difference there is after you've subtracted dark and bias.

Thanx Eden - I think the 21 x near 7min subs at F4.7 assisted in collecting the fainter blue signals. The introduction of noise (through streaching) I tend to deal with as it turns up during processing, will get to adding the Dark frames eventually - when I pluck up some courage

No worries Marc - I used to have a problem with Black clipping and too much contrasts - so may'ave under done this in that sence
Ive saved a few during processing stages - so can start on another half way through and go from there, Cheers

Thanx Erik - been sidetracked away from a repro, getting to it, eventually
