M20 Trifid Nebula

This is my 1st attempt at M20 Trifid Nebula captured in Sydney
No very clean or sharp and still noisy.A bit disappointed as this image has over 2 hours of data and conditions were ok for Bortle 8 skies with no moon around , just both neighbours flood lights on for no apparent reason
65 x 2 minute dithered guided subs
20 x darks
ISO800
6” f6 newt
HEQ5 mount
Guiding was terrible too 1.50 to 1.90 arc sec error , the dithering was upsetting the mount to much. Threw away quite a few subs
Stacked in DSS
Processed in Startools

Thanks for looking
