Description

The lesser known globular companion of the Great Hercules Cluster. I had issues with flats and recorded the luminance and the colour frames in two different years (talk about priorities!). Re-precessed the integrations with PI for a better colour balance than the original. Still a very nice compact globular deserving more attention it gets.

While I tried to get around the various issues with colour flat-fielding (never easy in a light polluted environment) with some success (thanks to PI) others I couldn't get rid of, namely the ghosting of the primary visible just above the cluster.
