Huehnerhoff During checkout I did get a ringing of the alt drives after an axis init. Slewing stopped the ringing. Poor, variable seeing the entire night. Weird pointing issues during the night. The pointing seemed to change position, although it also looked like the changes were along altitude. The pointing was checked on both the na2 guider and dcam with a track /pterr. There was no indication of a pointing error through these tests.
