NGC 2775

With more than 180 references in astronomical journals, NGC 2775 is of particular interest to astronomers for a variety of reasons. First NGC 2775 is a peculiar blend of spiral galaxy with a smooth bulge in the center. The spiral pattern starts very abruptly outside of this region showing a mind-boggling complexity (especially at higher resolutions). The star formation is confined to this ring of tightly wound arms. Indeed, this galaxy has been host to 5 supernovae explosions in the past 30 years. While this picture seems to show a quiet and delicate swirl, keep on eye on this galaxy; you never know when another star will explode in this busy place some 60 million light years away. NGC 2775 is similar in structure to galaxies such as NGC 2841 and NGC 488.

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 = 90 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
