NGC 2903

At a distance of 20 million light years away, NGC 2903 is a very bright spiral galaxy in Leo. It is interesting to note that Messier missed this galaxy in his searches of Leo. As with most face-on spiral galaxies it is easy to see the dust lanes and emission nebulae (pink regions).

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 = 75 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
