LRGB color production was used to create this image.

One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was 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 = 15 minutes binned 1x1

Red = 5 minutes binned 2x2

Green = 5 minutes binned 2x2

Blue = 5 minutes binned 2x2
