NGC 5128 Centaurus A under Sydney skies

Saturday evening in Sydney was the best nights imaging I’ve had for 6 months or longer . I was surprised at the number of single stars I could see under our terrible light pollution. Usually look up and see only a handful
Conditions were really good with no dew , no moon , very light westerly and more importantly my neighbours either side of me didn’t have the huge light spill from their flood lights blasting my backyard ( lucky I guess ) Apart from issues I’ve had with my optical train of my little Newt , I managed to put together a reasonable image ( still haven’t got the field nice and flat with round stars across the whole field , a work in progress)

6” f6 Bintel GSO newt ( Bintel have advertised this scope primarily for visual use since 2016 )
