Seeing in Brisbane was quite good last night, at least out near the bay. Between about 10pm and 2am, it was very good, though not perfect - there seemed to be at least one semi-turbulent layer up there, as seeing would go from good to very good and back again every few minutes in different parts of the sky and there were some clouds doing their wispy appearing/disappearing act from time to time. Another supporting sign was the dew and the "relative" cold - not especially humid by the forecast, but a lot of dew and I was rugged up - that sky felt cold and my 'scope was plenty cold by midnight.

The views were enjoyable and I got some good snaps of Jupiter, Mars and Saturn. I will see if I can extract any decent details from the images ...

I agree that 'scope cool down time is vital. Even though I've been doing visual astronomy for a while now, and thought that 2 hours of cool down was plenty, I've recently found (I think) that the for good photography, even longer cool down times improve performance. In fact, the longer/colder the better.
