Abell 2218 - Galaxy Cluster
Abell 2218 is a massive galaxy cluster around 2 billion light years away, and contains thousands of galaxies. Its immense gravity bends and focusses the light from more distant objects, in a manner similar to light being refracted through a normal glass lens. This effect, called "gravitational lensing", was predicted by Albert Einstein.
The cluster is about 2 billion light years away, while the distant galaxy is much further away, seen as it was over 11 billion years ago
The image comprises of:
Luminance - 10 hours.
Red - 3 hours.
Green- 3 hours.
Blue - 3 hours.
Total - 19 hours
10 and 15 minute subs.
Acquisition - Planewave 12.5" CDK, PME, QSI 583 8WSG CCD, Lodestar auto guider, TSX, Maxim DL. Astrodon LRGB filters.
Processing Pixinsight 1.8 - I have had this data set around for a while and to be honest forgot about it.
