Objects Session Notes
C/2017 T2 (PanStarrs) - Comet C/2019 Y4 (ATLAS) - Comet M10 - Globular Cluster Rose 25 - Compact Galaxy Group (PGC 54033 et al) Variable Stars (photometric monitoring) - FU Ori, DY Per, RR Tau Nearby Stars (astrometric monitoring) - Barnards Star, Groombridge 34, LAMOST-HVS1, Scholz's Star
- All night session (11.2 hours total), but shutter closed through middle of night due to cloud.
- Main aims of the session was to acquire images of a selection of deep sky and comet objects - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: -1°C (min)
(Dew heaters on auto)- CCD Temperature: -25°C (68% av. power) - Notes from 2020-02-26 >>
