WO Redcat51 @F4.9 and Atik460ex

Frames:
Atik Luminance 1.25: 21x600" (3h 30') -15C bin 1x1
ATIK BLUE: 8x300" (40') -15C bin 2x2
ATIK GREEN: 7x-15" (58' 15") -15C bin 2x2
Atik RED: 16x300" (1h 20') -15C bin 2x2
Integration: 5h 28' 15"
Flats: 16
Flat darks: 16
Bias: 10

Just two nights data with a bright Moon in both , one night was imaged remotely while i was at the OAS meeting and then from Caroles.Will get lots more detail in order to bring out the Dark nebula.

Your processing is getting much better Roger, that's a nice result.  Stars are better as well and of course I was on-hand while you were imaging this remotely, very clever.

That's definitely one of your best images.  You have good star colours and the dust has come out well.

Thanks Mark , I seem to be getting good results with last few targets with Calibration and integration and a little processing in Pixinsight then finishing off in Photoshop.

That’s a great result Roger and the Dusty bits have come out well.

Very good indeed Roger!  I think you can afford to bring out much more nebulosity as your sky level is very dark.  Your star colours are spot on.

Thanks all , really getting good results with Pixinsight since i was tutored at Notgrove DSC by an Astro Colleague and a couple of inpromtu sessions with Peter Shah,after which i have been using Dark Flats  , and Bias when calibrating as well as Flats.
