Coma Cluster (NGC 4889 and NGC 4874)

Click on image for larger version.

Located in the small constellation of Coma Berenices, this cluster contains more than 1000 galaxies. Almost every object in this image is a galaxy. This cluster of galaxies is several hundred million light years away and is moving away from our own galaxy at 7000 km/sec! In fact this cluster is so large that it takes light several million years to travel from one side to the other!

Equipment

16in RC Optical Systems telescope Operating at f/8
Paramount ME Robotic Telescope Mount
SBIG ST10XME CCD camera with color filter wheel

L R G B color production was used to create this image.

Luminance = 180 minutes binned 1x1
 Red = 20 minutes binned 2x2
 Green = 10 minutes binned 2x2
 Blue = 20 minutes binned 2x2
  • One iteration of L-R deconvolution (sharpening) algorithm using CCDsharp was applied to the luminance image.

  • Flynn Haase helped process this image.
  • Digital Development (DDP) via Maxim/DL was also used in order to display the the very dim and very bright details of the image simultaneously.
