20in RC Optical Systems telescope Operating at f/8.4
Paramount ME Robotic Telescope Mount
SBIG ST10XME CCD camera with color filter wheel

L R G B color production was used to create this image.

Luminance = 60 minutes binned 1x1
 Red = 20 minutes binned 2x2
 Green = 20 minutes binned 2x2
 Blue = 20 minutes binned 2x2
  • Two iterations of L-R deconvolution (sharpening) algorithm using CCDsharp were applied to the luminance image.

  • Al Kelly was instrumental in removing a very bad blue gradient.
  • Digital Development (DDP) via Maxim/DL was also used in order to display the the very dim and very bright details of the image simultaneously.
