I don't normally see such good contrast.

Greg this is only from four minute subs taken last year. Apart from an F3 optic and an Atlas focuser and a 10 position CFW on a MX mount my major problem is colour gradients. At F3 they are horrific! If you can collect dim stuff you also collect all the light pollution.
I am going to collect some 8 min subs tonight of the bottom bit of the Coal Sack.
