Objects Session Notes
46P/Wirtanen - Comet Photometric Monitoring - Variables - AM Her, DY Per
- AM CVn , SS Her, CY Lyr attempts failed
Astrometric Monitoring - Nearby Stars - None
- Evening Session (3.7 hours duration) .
Poor sky transparency
- Main aim of the session was acquire images of a selection of nearby stars, variable stars and deep sky objects , and perform software testing.' - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: -2.5°C (minimum) - CCD Temperature: -25°C (70% av. power) - Notes from 2018-12-23 >>
