Although it is easier to process than 47 Tuc, I agree getting it right can be a little tricky.

Yeah that tweak makes all the difference. Very nice.
They look better usually with medium focal length although the smaller globs of course require longer focal length.
They aren't necessarily an 8 hour image. The best are often quite short in total exposure and short sub exposures. You don't want a weak washed out look either from lack of exposure time - so there is a judgement point there. A 5 hour Omega Centauri probably would not look any better than a 45 minute one. You could possibly do some short and some long and do an M42 style composite.
Star colours need to be really brought out. Daniel Verschase was the master of that. His globs set the standard nobody has bettered yet. He seemed to get golden stars in his that look fabulous. I think he used selective colour a lot to achieve that.
Greg.
