Brief rant:
After realising that there would be good transparency and decent seeing, I went for a half hour drive to the upper Yarra Valley for some darker skys.
However, once I was set up, there was hardly any detail on Jupiter, no Cassini division on Saturn, stars appeared blurry at 60x and sometimes even at 40x. Hmm, I thought, maybe the scope isn't cooled down enough yet, but it didn't get any better. I then realised the stars were twinkling like crazy. Well, no moons of Uranus or Neptune then. I cut my losses and went for some galaxies and M42.
At some stage, the seeing was so bad that the components of sigma orionis appeared to slightly move relative to each other.
I've never seen it quite that bad. It's amazing how conditions change. A month ago Jupiter held steady at 270x.
