A super frustrating night with several tracker failures and the auto-collimator failing to engage on almost every pointing. We lost some observations to bad seeing and, finally, high humidity. We even had a slit-mask jam at just the wrong time, as we tried rapid follow-up of a ZTF alert. We were not able to fully take advantage of the excellent 0.8" seeing at the end of the night, due to the tracker.
