I had a look over this - good skills needed to avoid a noisy background sky with globular clusters. Bortle 3 skies + cooled camera + several hours of integration will have helped.

Something to aspire to there! The telescope looked good - a 12.5 inch astrograph - a very sharp image at about an arcsec per pixel for the scale of the image. The colour handling during processing was superb -- I wonder whether this is the sort of target where it really works better to be using a mono camera rather than an OSC. The very tiniest stars that are resolved in that image are sharp and white -- it is all too easy to get them more blurry and sort of off-white.

It is also interesting that there was about 12h of data there from a big F5 telescope -- for such a bright object
