Despite one of the weirdest auto guider profiles the image turned out sort of OK. I normally use 5 second autoguider exposures but somehow CCDAP set it to 20 secs for some of the images (smooth)
Because of the effects of blooming on these very bright stars, these subs are all short (2 mins). The data:
Taken last night 20/2/2010
RCOS 12.5", ST8. Borg ED77 + RGH
L 48 * 2 mins unbinned
RGB 18 each * 2 mins binned 2*
Initial processing in CCDStack (Callibrate, stack, noise reduction, deconvolution)
Final processing in PS (Luminance layering, curves etc).
I'd appreciate all comments
