NGC 536: Hickson 10

This group of four galaxies is around 220 million light years away. The collection of spiral galaxies on the left side of the image include: (from top to bottom) NGC 542, NGC 536 and NGC 531. The warped arms of the latter two galaxies strongly suggests they are interacting with one another. NGC 529 on the right side of the image is a bright lenticular galaxy. This galaxy probably used to be a spiral like its neighbors, but either due to gravitational interactions or a lack of material to form more stars has relaxed to this smooth almost elliptical (but not quite) like state.

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 = 90 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 20 minutes binned 2x2
