Objects Session Notes
AT 2022fnb - CV Type Transient AT 2023dwm - CV Type Transient Variable Stars (photometric monitoring) - None Nearby Stars (astrometric monitoring) - 61 Cyg
- All night session. Images only successfully captured from 3 targets. Other targets failed due to a dome pointing issue that caused the telescope view to be oculuded by the dome roof. - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 8.5°C (min) - CCD Temperature: -15° C - Notes from 2023-07-22 >> -
