I spent a little time out working with my SM40 on my 98FLT today, but boy was it hot. It had to be about 38C in the observatory. While the view was great at the eyepiece, I couldn't squeeze more than a few FPS out of the DMK, meaning that any images were over-exposed. I'll have to give it a shot again and see whether I can get it running up at 60fps again where it works nicely.
I was able to use things and have them running very nicely they day I picked up the SM40 with great results (June 28). It was another hot one, but for whatever reason was able to record at 60fps. Connor helped out with the focusing and imaging, and we were able to image a couple of fantastic prominences; one appearing to me multiple arches or a hedgerow, the other more of a fountain.
