Objects Session Notes
Jupiter - Planet C/2022 A2 (PANSTARRS) - Comet C/2022 E3 (ZTF) - Comet Kepler-17 - Exoplanet Host Star B33 - Horsehead Nebula (IC 434) M31 - Spiral Galaxy (Andromeda Galaxy) M33 - Spiral Galaxy (Triangulum Galaxy) M35 - Open Cluster M37 - Open Cluster M38 - Open Cluster M42 - Diffuse Nebula (Great Nebula in Orion) M45 - Open Cluster (part) M67 - Open Cluster M95 - Spiral Galaxy NGC 2158 - Open Cluster (H VI-17) - IC 1756, UGC 2926, UGC 3044, IC 1874 target attempts failed (images rejected because of diminshed & uneven illumination due to condensation inside the LX200 telescope tube) Variable Stars (photometric monitoring) - None - FO Ori target attempt failed (images rejected because of diminshed & uneven illumination) Nearby Stars (astrometric monitoring) - None
- Attempted All Night Session session (12.3 hours) with the plan of make extended photometric runs on AT2022evv (RR Lyr type star) and Kepler-17b Exoplanet Transit, however plans were abandoned due to condensation inside the LX200 telescope tube that caused diminshed & uneven illumination.
(the problem was a consequence of an incident in the previous session when accumulated snow from a snow shower slid off shutter onto front of telescope when the shutter was opened upon session resumption).
Apart from an image of Jupiter Moons & baseline images of Kepler17 other images taken through LX200 were rejected.
In order to still get something out of the observing session operations were switched over to using the TS80 Secondary Scope + ZWO 178MC camera for imaging, with the LX200 used in support for centering & guiding.- 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: -2°C (min) - CCD Temperature: -25°/-30°C - Notes from 2023-01-18 >> Note: there were no images associated with the following S1090 session attempt , and therefore the 'Next Session' arrow jumps straight to the S1090 session.
