ARP229-galaxy cluster
This image shows the distant galaxy cluster ARP 229 in the constellation of Pisces that is made up of a composite of 125 frames - 300 seconds each amounting to a total exposure of 10 hours 25 minutes. The stellar limiting magnitude of the image is around +19.6 mv that is around 2300 times dimmer than the faintest star visible with the unaided eye.
Many of the galaxies in the image have been identified with the brightest galaxies showing some kind of structure. Some faint galaxies remained unidentified due to the lack of available catalogues that reach deeper magnitudes.
Image was taken over three nights through a 10 inch Schmidt-Cassegrain telescope . Camera employed: unmodified Canon 1100D DSLR working at ISO 800. Quantum efficiency of the camera is rather low at 36%, hence long exposure times were needed to capture some of the faint galaxies.
