Looking very fine Bart.
Just looking at the numbers, the background has quite a blue cast, but even if I fix that, the glob is slightly too blue. Although globulars contain a smattering of very salient blue stars due to mergers, globulars, with their extreme age of around 10 billion years, cannot on average be blue, because blue stars are so hot they only live a million years or so.
Despite that minor quibble, a lovely image.
Best,
Mike
