NGC 5139 Omega Centauri under Clear Sydney Skies

Captured a quick hour on the Omega glob last night in Sydney under a 50% waxing moon with pretty good conditions.
Although 47 Tuc and M22 are my favourite Globs , Omega has the “Wow factor” when someone sees it for the first time.
Same rig my little 6” newt and EQ6-R mount
2600MC camera -10C , Gain 101
Guiding was excellent ( 0.50 to 0.60 total )
62 x 60 sec subs ( dithered every 3rd )
Flats and Bias
As always in Sydney, battled with heavy gradients but having the atmosphere fairly stable makes a huge difference
Stacked in DSS
Processed in Startools v1.8 , Linear OSC
Used the Spatially Variant PSF Deconvolution module in Startools to good advantage , reduced atmospheric blur and tightened up the Stars
