We saw a strange striation pattern in some images it looked like the old syncing problem, but really was a problem with the controllers. We resolved the problem by cycling the power of the Monsoon controllers.
The controller problem returned starting at image obj_0478. WE moved the telescope to zenith and I went to the Cass cage to power cycle the Monsoon electronics.

Had steady focus for he first few hours of the night and the delivered image quality was 0.8¨ (2 pix). Used that time to calculate the focus offsets among the different filters. Then performed tests to characterize the narrow band filters (164, 2124, and 2168).
