NGC 3293 Gem Cluster

First nights imaging in Sydney last night for over 2 months due to fires and flooding
NGC 3293 Gem Cluster adjacent to Carina Nebula
6Ē f6 Bintel GSO newt on a HEQ5 mount
Canon 600D unmodded with Baader coma Corrector
ISO 800
50 x 90 sec dithered guided subs
25 x darks
PHD2 guiding 1.20 to 1.50 arc sec error
Frame , Focus and Capture with BYEOS
Goto and tracking EQMOD ,StellariumScope and Stellarium
Stacked in DSS
Processed in Startools v1.5
Seeing conditions, very good for Bortle 8 suburban
Intermittent clouds most of the night until 12.30 am which made capturing usable subs a long process ( stopping and starting PHD2 and Frame Capture ) Finally got to bed at 2.30am
2 images , wide field and cropped

Thanks for looking , comments welcome !

Thanks Carlton
Appreciate the comments
Another 20 or 30 subs would have been nice and resulted in a little bit more nebulosity around the cluster and top right hand area but the focus was drifting a bit after an hour and had to correct it. Also my auto focuser was playing up and needed a tweak with a tiny Allen key to get it going again , probably due to not being used for some time.Lots of tiny issues which brought me closer in time to a rising 60% waning moon, so it cut my night short ( I donít use filters on my DSLR )
This seems silly but it was great to get out under clear Sydney bortle 8 skies again after a long time ( almost 3 months) although I did manage to image from my weekender ( Bortle 3 ) down south during January but only 2 nights
