LRGB color production was used to create this image.

Most of this data was taken through intermittant clouds. The effective exposure time is therefore much less than

the total integration time of 3 hours for the luminance.

The AO-7 unit was used to acquire 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 = 180 minutes binned 1x1

Red = 30 minutes binned 2x2

Green = 30 minutes binned 2x2

Blue = 30 minutes binned 2x2
