NGC 5139 Omega Centauri Globular Cluster

Last night we had a rare clear night in Sydney with a 50% waxing moon so imaged an easy target in NGC 5139 Omega Centauri. Atmospheric conditions were poor with a heavy dew around as guiding was ordinary at +1 arc sec
Haven’t imaged this target for about 2 years

6” f6 GSO newt
EQ6-R mount
ZWOASI2600MC set at gain 100 lowest read noise
25 x 90sec dithered guided subs
Flats and Bias
EQMOD and Ascom Stellarium
APT
PHD2 Multistar guiding
Stacked in DSS
Processed in Startools V1.7 OSC linear data set

Pretty noisy data but Startools did a good job of mitigating without loosing too much res
Only a light Decon at 1.5 pixels

Comments welcome
Thanks
