Best of AOP - Galaxies


M61 is one of the major members of the Virgo Cluster of galaxies. It is comparable in size to our own galaxy. Though a barred spiral, deep images such as this make the bar in the nucleus of the galaxy less obvious. This galaxy has an extraordinary number of star forming regions (HII, pink areas). An image with greater resolution would certainly show even more evidence of active star formation. At distance of 60 million light years away M61 seems to float in the foreground of several distant galaxies.

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
