Stephen,
I managed to get an ISS passover tonight. Out with the scope for a crack (after cleaning mirrors, yay)
Again, 30 minutes before passover, little or no cloud cloud, come ISS time, clouded over, jeeezzz

Melbourne weather is "check for clouds, 2 minutes before you use the scope", hahaha.
Anyway, up it came this time and was with an orange tinge to it, even at 25 degrees Alt.
After navigating the heavy to fine misty clouds, I got the ISS in the scope, jeez, fast moving bugger. Hahaha. I couldn't get much definition, as I was jittering around too much

But finally got to see it through the 12".
