Imaged with a Northern Galactic members remote telescope in Australia, http://3.bp.blogspot.com/_9HcYqbvUc4s/S-b4XGoaKCI/AAAAAAAAEVg/lmCuJMbTT-c/s1600/NGTelescopeL.jpg

16" RCOS ja Apogee U9000 camera.
LRGB combo.
H-alpha 5x1200s, O-III 2x1200s, S-II 2x1200s . Dark and Flat calibrated.
Raw data is shared with Petri Kehusmaa and J-P Metsavainio

Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations.
Levels, curves and color combine in PS CS3.
Narrow band lines are mixed to a HST-palette (Used generally with Hubble Space Telescope)
Red=S-II, Green=H-alpha and Blue=O-III
