Description

One of the two 'great' southern hemisphere globular clusters, 47 Tuc (NGC104) is located in the far southern constellation of Tucana. In previous imaging attempts I'd always ending up washing out the small, bright core of the cluster. To better resolve the central stars, I tried a form of lucky imaging, collecting 1000 x 1 sec exposures in R, G and B and keeping just the best 300 of each. This worked better than I'd hoped, allowing stars to be resolved right to the core, whilst still providing enough exposure to see the fainter outer reaches.
