MDM Trouble Report for 2017 Mar 25 Telescope: 2.4m Observer(s): Jessica Klusmeyer (MDM) Instrument: OSMOS R4K Problem(s) Encountered: What a night ! Noticed the issue when trying to focus for the start of the night. Stars would not focus, mostly crescent/ triangle shape. Tried moving focus to extremes but did not help. Parked the scope and started to look through trouble reports Went into computer room and noticed Air Bag system was showing Error from cycle Not Ready on several lines there was another error message about a certain cycle when error occurred but did not write it down At first thought it was an issue similar to Airbag Pressure Failure and tried typing h1 on air bag keyboard. Nothing happened so then assumed it was an issue where the computer needed restart. Restarted the computer and typed support into system. Reading went to 30lbs so assumed that fixed the problem (if that was the cause at all) went back out and everything seemed fine. I assume it was actually something with the air bags from the previous report ( Oct 13 2012) that mentioned the stars being smeared + the error messages on the computer Back on sky had difficulties with pointing. not sure why, took a long time to correct, but got there was using tilt sensor reading but found needed to expand region to 2k to locate stars Went to first target of the night and prospero showed IC DOWN and TC Down. Thought this was an error and went to zenith to trouble shoot but a quick fix of restarting prospero with tcinit in command window worked Things appear to be working now and I had no issues with the rest of the night ------------------------------ Submitted on 2017 Mar 26 [6:29:36]
