MDM Trouble Report for 2019 Dec 06

Telescope: 2.4m
Observer(s): Rupert (MDM)
Instrument: OSMOS/B

Problem(s) Encountered:
Lost pointing big time at the end of the night. Kept resetting
the offsets to the wrong objects. When I set the telescope to
zenith in the end, it was visibly not at zenith, especially in 
DEC. Moved the telescope to zenith by eye (using the orange 
tape on the telescope for RA and a spirit level for DEC). The
zenith distance according to the TCS after I did that was 4.7
as opposed to 0.2 as it usually is. Decided to see if my by-eye
zenith offset was decent by slewing to a nearby bright star.
Couldn't find it. Slewing back to zenith put it in the position
I had it. I left it at that, so significant improvements to
pointing still need to be made.
