Problems: 

Near the end of the night, we arrived at a new target and obtained acquisition images of the field and the slit, but they were mosly blank and did not show the field or the slit. Several more images were obtained, but the problem persisted. It was later found that the shutter was malfunctioning.

After most resets of the zero point of the telescope pointing, the pointing would drift by 10-20" from one target to the next (most of which were in the same area of sky). Once the offset in pointing reached >60-90", we would reset the zero point. This wasn't a serious problem, but acquisition would be a bit faster if the telescope maintained better pointing.
