Captured NGC 4594 Sombrero Galaxy (magnitude 8.2 ) the other night in Sydney ( Bortle 8 skies ) with an 84% waning Moon up and annoying neighbours outside lights blasting my backyard on both sides ( a great recipe for Astrophotography)
Anyway we struggle through the obstacles to try and get some sort of image out of it all

6” f6 Bintel newt on an EQ6-R Mount
Canon 600D with Baader coma corrector ( no filters)
Orion 60mm guide scope with helical focuser and ZWOASI120MM guide camera

PHD2 guiding ( guiding error was atrocious above 2.0 arc sec error , RA and DEC saw toothing badly so put it down to bad seeing however guide star SNR was hanging in there at 37 to 40 , tried everything to dampen it but in the end tried the Predictive PEC algorithm and after a few worm cycles eventually steadied the ship and stabilised around 1.8 arc sec error. Proof in the pudding was round stars in each sub for hours )
