Hey thanks so much everyone
It is always a challenge to present globs faithfully, bit like galaxies really, they should generally be much brighter in the core but the temptation is to go for high res in there and as a result the overall dynamics don't look real, not that it is a bad thing as resolution may be the thing you are really after of course. Here though I tried to showcase this mighty cluster in a way that had
some resolution in the core but given the almost infinite number of stars in there it needs to also have a glow and not be
sharply resolved to look real in my opinion...
I also tried to get the more bronze/gold colour in the red giants rather than sturated yellow and tried to keep the blue straglers subtle.
Anyway, just another madness prevention exercise
