LRGB color production was used to create this image.

Data taken on two different nights. The seeing was very poor on both nights.

Bob Ferguson and Richard Desruisseau also acquired data for this target.

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

Luminance = 90 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
