Hi all
Finally had a chance to try imaging with my rig under dark skies, setting up in an Aunt's backyard in the southern edge of Gloucester, they skies way darker then Newcastle. I used the 300mm lens from Bert and my modded 350D. The evening was perfect, 100% clear , only slight breeze and fairly dry.
Here is the Horsehead Nebula, 9x10 mins ISO400. UV/IR filter 300mm f1.8 stopped down to f3.5. Hand guided as usual while watching the Friday night NRL on my laptop!
At my place at ISO200 the subs are very light but at Gloucester even ISO400 are fairly dark, and the Horsehead shows strongly in the unprocessed subs.

Captured plenty of brown dust. Only thing , needs a cooled camera as thermal noise now more dominant than light pollution.
