Christmas Tree Cluster and Cone Nebula (NGC2254)
NGC 2264, The Cone Nebula: November 29, 2006, full color ST9 exposures through 70mm guide scope at f/5.7, red, blue and green channels only. (R 15x1min, G 5x1min, 9x1min). Luminance images taken but were not used in the final image. Luminance exposures were with the H-alpha filter, 11 exposures at 5 minutes each. I used noise filter in AIP4WIN and gradient remover in MaxIm DL. (Images were reduced in AIP4WIN).
Taken from the CSU, Fresno Campus Observatory.
