MDM Trouble Report for 2002 Apr 12 Telescope: 2.4m Observer(s): Halpern, Gezari (Columbia) Instrument: Mk III Problem(s) Encountered: 1. Guider seems not to be communicating to the telescope. Program is running, and it sees stars in the box, but telescope still drifts. Tried recommended parameters for slit guiding, but it didn't work. Had to hand guide all night. 2. Finder camera is not receiving any light, either in filtered or open position. ------------------------------ Submitted on 2002 Apr 12 [4:20:47]
