M22 Globular Cluster in Sagittarius

Imaged M22 last night in Sydney with my 6” f6 newt on the HEQ5
Haven’t imaged this object since September last year so I compared the both images and this time was a significant improvement with no coma
45 x 2 minute dithered guided subs
20 x darks
Canon 600D with Baader coma corrector
ISO800
PHD2 ( 1.4 to 1.6 arc sec error ) low to medium dithering knocks my HEQ5 around a bit and takes a lot longer to recover compared to my EQ6-R mount
BYEOS
Stacked in DSS
Processed in Startools

Thanks for looking , comments welcome
