Wishing Well cluster
Image of the - oh so beautiful - Wishing Well cluster (NGC 3532). It's probably my favorite open star cluster...
NGC 3532 (Caldwell 91) is an open cluster some 405 parsecs from Earth in the constellation Carina. Its population of approximately 150 stars of 7th magnitude or fainter includes seven red giants and seven white dwarfs.
The cluster lies between the constellation Crux and the larger but fainter "False Cross" asterism.
Image acquired with the CHI-2 telescope (from a one click observation)
Total exposure time "only" 40 minutes. 2 subframes of 300s with each filter (LRGB)
