Best of AOP - Galaxies

NGC 4731

This very dim galaxy appears a bit bent out of shape due to the nagging gravitational effect of its neighbor, NGC 4697. At an estimated distance of 65 million light years away NGC 4731 is on the far side of the Virgo Cluster of galaxies. The galaxy has a few hotspots of star formation, but is otherwise fairly demure in appearance. The background is mottled with galaxies perhaps hundreds of times more distant.

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.

The average FWHM for this image is 2 arcseconds.

Luminance = 90 minutes binned 1x1

Red = 20 minutes binned 2x2

Green = 20 minutes binned 2x2

Blue = 30 minutes binned 2x2
