MDM Trouble Report for 2017 Dec 22 Telescope: 2.4m Observer(s): Weil, Fesen, Gasque, Sosanya (Dartmouth) Instrument: OSMOS/B Problem(s) Encountered: Over the course of this observing run we have noticed that when we change the focus using the GUI, the guider has been freezing, especially with movements more than ten units. Simply stopping and starting the guider again seems to fix the problem. Twice during the night the telescope jumped so far that the guider could not find the star. We had to stop the observations and reposition the telescope. (Note typing s will abort an exposure and save it when using Prospero.) ------------------------------ Submitted on 2017 Dec 23 [5:52:06]
