20in RC Optical Systems telescope Operating at f/8.1

Paramount ME Robotic Telescope Mount

SBIG ST10XME CCD camera with color filter wheel

LRGB color production was used to create this image.

Very poor seeing conditions made the color balance of this image difficult to attain.

Two iterations of L-R deconvolution (sharpening) algorithm using CCDsharp were applied to the luminance image.

Digital Development (DDP) via Maxim/DL was also used in order to display the very dim and very bright details of

the image simultaneously.

Luminance = 90 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
