MDM Trouble Report for 2007 Nov 10 Telescope: 2.4m Observer(s): Watson & Prieto (OSU) Instrument: CCDS and Retrocam Problem(s) Encountered: The dec encoder stopped working two times during the night when we tried to observe two objects in the west. This didn't allow us to guide and observe those objects. The first object was at HA~1hr50m and DEC= -0:15 (airmass=1.4); the second object was at HA~2hr59m and DEC=00:08:40. We tried slewing away and then going back to the position but it still didn't respond. ------------------------------ Submitted on 2007 Nov 10 [6:08:06]
