MDM Observatory 2.4m Telescope Observing Report for 2021 Jul 06 Observer(s): Rupert Institution(s): MDM Instrument: OSMOS/B Worked for 7.5 hours (most of the night) Conditions were Non-Photometric most of the night. No equipment or software problems were encountered. Seeing and Weather: Clouds all night. Beg: Seeing 1.4 arcsec, Overcast, Winds Light & Variable Mid: Seeing 1.3 arcsec, Overcast, Winds Light & Variable End: Seeing 1.0 arcsec, Overcast, Winds Calm Observing Summary: Determined today that the issue with the rotator has something to do with the failsafe brake. Removed it from the motor assembly and was able to use the rotator without any issues. High clouds covered the sky all night. I was able to punch through it with brighter targets. ------------------------------ Submitted on 2021 Jul 7 [3:57:39]
