Well here is my first serious attempt using my Sbig 2000XM and RCOS 12.5 inch. It is lacking a flat field and I accidentally lost a couple of the green subs. So I'll reshoot those and get more.
M20, LHaRGB 45:45:10:2.45:10 Ha and L 1x1 binning and 15 min subs and colour 2x2 all at -20C.
Taken from my backyard observatory (pic of it a few posts earlier) in Sydney Australia on a very clear night (yeah, at last!)
Calibrated and registered and colour combined in CCDStack, final levels in Nikon Capture Editor.
RCOS 12.5 inch, AP .75 telecompressor at F6.75, Tak NJP mount, Sbig LRGB filters, Schuler 10nm Ha filter, The Sky V6.0 and Telescope Tracer (Tak planetary program).
It took as long or actually longer to process than to image!
Apart from the flat field and a bit of graininess in the green any suggestions?
Cheers,
Greg.
