      My 47 Tucanae NGC104

      This bright cluster of stars is 47 Tucanae (NGC 104), shown here in an image taken from TelescopeLive in Chile. This cluster is located around 15 000 light-years away from us and contains millions of stars, some of which are unusual and exotic.

      Globular clusters are challenging as we by no means can resolve their full potential. But with about 3 hours using a multitude of exposure time the result is rewarding.

      This is an area where AI aided processing have issues so I was forced back to traditional MLT, HDRMT , HSVRepair, Curves transformation and other methods to get a reasonable final image.
