Session Notes

M31 - Spiral Galaxy with Extragalactic Nova 2022qzf Minkowski 1-79 - Planetary Nebula (PLN 93-2.1)     Variable Stars (photometric monitoring) - Z And, SS Cyg      Nearby Stars (astrometric monitoring) - HH And, Groombridge 34, EV Lac

- Although intended as an all-night session, an AstroMain program crash just before starting Near Zenith Focusing, meant there was a signficant delay until the issue was noticed and resolved by installing a new corrected version of the program. After restaring observatory software the effective session  length was 1.6 hours.     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 12.5°C (min) - CCD Temperature:  -10°C - Notes from 2022-08-18 >>
