Combine), LRGB channel registration, equalization, central gradient removal -
Astroart. Curves, Levels, LRGB combine and finishing - Photoshop.
Final color Calibration with eXcalibrator. This image is a straightforward LRGB
combine with Luminance layering. Final Image size is
approximately 1800x1348. North is up in this
image. Galaxies NGC4874 and NGC 4889 are centrally prominent in
this image of this galaxy cluster - the Coma Cluster . Many of what appears to
bestars are actually member galaxies of the Coma Cluster. This field is in the
constellation of Coma Berenices. Other NGC objects in this field are
NGC 4872, NGC 4921, NGC4911, NGC 4895, NGC 4860. The Coma Cluster's
distance from Earth is approximately 320 to 370 million light years. This image replaces and earlier
image that can be seen in the Archives
here . Horizontal FOV is 55' Image center is approximately - Equatorial 2000: RA: 13h 00m 16s Dec: +27°58'03"
