My final image of M17 this year on a clear Sydney night
Bortle 8 sky
6” f6 Bintel newt on a HEQ5 mount
60 x 2 minute dithered guided subs
20 x darks
Canon 600D with Baader coma corrector
No filters
PHD2 guiding ( 1.20 to 1.30 arc sec error ) I noticed guiding improved ( RA smoother )as M17 descended in the west which contrary to previous experiences. The rebalancing of the mount with a new counterweight extension rod may have something to do with it ?

Great images Martin esp with bortle 8 skies.
Only just discovered what bortle means its pretty amazing that you get anything out of bortle 8.
Cheers
