Hi All.
M20 Nebula in Colour mapped Narrowband. (click for big)
Taken on an RCOS 10" RC Scope at f9, SBIG STXL6303E Camera and PME mount at itelescopes Siding Spring Observatory.
13hrs of 3nm Ha, 40 min subs bin1, 4 hrs , 20min each of 3 nm SII and OIII 20min subs bin2.
Processed with CCDstack, Star Tools and Photoshop.
Ive had a go before, but I got way more detail this time, and left the colour a bit more subdued. The odd hue works I think.
Ive left the background up a bit, theres a bit of extended dust cloud there thats oft clipped.
Star tools, now that ive fiddled for a while with it, has proved very handy with its noise tracking feature , makes finishing in PS a pleasure without worrying about noise or loosing detail.
Dark Skys rock too
