Ok Allan understand. I think Fizics might be trying to go to Coolah later this week. I might just stay home this time, save some money, and image from the observatory (no power management issues or generator neded at home), and I am expecting a call from the guy that bought my 16" dob who is driving up from Victoria to pick it up.
BTW Sky Quality Metre reading from my observatory last night at 2am (when I was packing up) was 20.86 - good enough for my purposes, and not too far off a real dark site.
