M19 Globular Cluster in Ophiuchus

I knew cloud was coming in around 10.00pm so decided to image a cluster last night
Ist image of M19 globular cluster in the constellation of Ophiuchus locates 28,000 light years from earth
It brightness is around 7.5 magnitude and is somewhat oval shaped compared to other clusters of similar brightness
High wispy cloud drifted across most of the early evening so guiding was affected
Out of 36 subs only managed to salvage 20
Seeing was average and Jetstream was running upwards towards 90kts ( high )
Stars throughout the core are not resolved that well
20 x 90sec dithered guided subs
15 x darks
6”f6 newt on HEQ5 mount
Canon 600D with Baader coma corrector
ISO 800
BYEOS
EQMOD and Stellarium
PHD2 guiding
Stacked in DSS
Processed in Startools

Thanks for looking , comments welcome
