Well, of course it was cloudy when I got home again but them miraculously around 9:30 PM a gap opened up in the clouds. That was all I needed to at least try the scope.
All up I had about 90 mins to play with the scope in the various configs through wispy clouds so it was not Ideal.
The scope feels nice, everything feels solid and tight.
Pointed at the moon and Jupiter and when defocused, there only seems to be the slightest Chromatic aberration although there was wispy cloud in front of Jupiter so hard to tell. I could not notice it at all when focused (but I was rushing)... so much to do so little time.

Next Test - QSI Camera with Flattener. Well that was a bit of a disappointment. The Orion flattener worked, but it is also a reducer which I was not aware of. The massively wide view on the CCD extended to fading rounded corners but evenly shown on each corner. Will play with spacers to see if that can be improved.

Final test was the only disappointment, using the A/O then the flattener then the camera is a bust for now as there is not enough in focus. Stars were Massive so I don't think a minor adjustment to spacers will help there but I will give it a try next time, or see if I can find a flattener that is not a reducer.

Event without the flattener, the few test images I did, showed only a little amount of distortion towards the corners, but I know its there as the stars in the OAG view were elongated.

That looks like it for the next week according to the forecasts (Unless another miracle window appears tonight :-) )
