Whilst waiting for Corona Australis to clear my roof I decided to image Omega Centauri in LRGB with 30 sec exposures. I used the new Normalized Scale Gradient script in Pixinsight, so far so good and it definitely is producing tighter stars and less gradients.

PHD2 guiding, SGP Pro for acquisition, Sharpcap Pro for PA and Pixinsight for calibration and processing.
Maate, there's hi res and something that my satellite said 'file too large' or something like that, your file is 200Mbyte!!
Anyway couldn't check it out, have another go

That's better, had a look at the hires.
I would try a few things to bring out more star colours.
You should see lots of blue stars, and even a few red ones if you get it right.
Maybe less LUM to avoid pixel saturation?
Maybe up the hue saturation?
Stretch a little less?
