Redone with another nights data from last night , brought out more dark nebula .




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.

Thanks Carole , yes on the stars thats just the LRGB data NO OSC data in there.

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.
