This morning I had an 89 degree high pass in perfectly clear weather just after a cold front moved through the area. Seeing was pretty turbulent but the transparency couldn't be beat. I tracked ISS right up to the zenith using my custom software for closed-loop optical guidance.

I'm also currently testing and patching ASCOM compatibility using a smaller NexStar SE scope and it seems to be going well so far, but I still need to do a field test on a real sat with that scope.
