Objects Session Notes
AT 2024aane - Transient (non-detection) M31 - Spiral Galaxy with Nova AT 2025kvc (non-detection) Realtime Pictures from Current/Latest Session >> Variable Stars (photometric monitoring) - None Nearby Stars (astrometric monitoring) - None
- Short session (2.4 hr). Short summer night. Clear skies
Session impacted by CCD Camera Issues & Bad Guiding (due to poorly focussed guide telescope)- 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature : 10.5°C (min) - CCD Temperature: -10°C - Notes from 2025-07-16 >> -
