Ok nothing to write home about and no 140hr marathon here, but as a test result, I'm happy.
Before the clouds became a pain in the R's I grabbed 4 X 5min subs in Ha on
NGC 6164. Of course, with such low data levels means very little processing was possible but it does hint at future possibilities.
The benefits of having an observatory were very clear, particularly at packup = close roller shutter, load data onto memory stick, shut down computer, cover scope, unplug power board, shut observatory door and roll up extension lead - finished, 10min

...setup is about the same too
Only slight issue will be, as others warned, I will need to be vigilant on watching that dome opening, with the scope in its current configuration there ain't a big window there...at the moment the Euphoria of having an observatory again is overlooking this aspect
So in the end it took just under 6 weeks from turning the first sod of Wallaroo Observatory to taking the first image from it, that's not too bad huh?
Look forward to my first full clear night now
