Dunk, I have had a couple of great nights up here over the last two despite the forecast it cleared after dark and allowed some good imaging runs with my cooled full spectrum camera running at -10C. Need to work out how much battery power I need to take to Bretti. If you can get up there for a couple of days next week it maybe well worth it.
Have a look here at just one (3 minute 30 second) test sub from Saturday night (yes there is a little dirt on the sensor around the middle right side):

Ken be aware that this coming weekend is the last weekend of the school holidays and Bretti is usually fairly busy then but by late Sunday they should be gone.
