Session Notes

ARP 104 - Galaxies (NGC 5216 & 5218) ARP 239 - Galaxies (NGC 5278 & 5279)     NGC 5693 - Spiral Galaxy (LCG 384 Member)     Variable Stars (photometric monitoring)   - R CrB CI Cyg, SS Her, U Her, FO Ori, FG Sge, V Sge, WZ Sge     Nearby Stars (astrometric monitoring)  - EV Lac

- Night session (6.6 hours) Session operated in fully automated mode with some  monitoring during the first part of the session - Main aim of the session was to test stability of AstroMain program after adding features and acquire to some images if possible. Conditons were forecast to be marginal.     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  Falling  to 13°C (min). Outdoors 12°C (min) (Dew heaters on automated) - CCD Temperature:  -10°C  (68% av. power) - Notes from 2019-09-21 >>
