LRGB color production was used to create this image.

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 = 20 minutes binned 1x1

Red = 10 minutes binned 1x1

Green = 10 minutes binned 1x1

Blue = 10 minutes binned 1x1
