Session Notes

38P/Stephan-Oterma - Comet 64P/Swift-Gehrels - Comet     HIP 20995 - Star     NGC 1662 - Open Cluster     Photometric Monitoring - Variables    - None       Astrometric Monitoring - Nearby Stars   - None

- Night Session (2.9 hours total, 0.8 hours images) . - Main aim of the session was to test the operation and use of a Pegasus Motor Focus Unit that was newly installed onto the TS 80mm f6 APO secondary scope - Opportunity was taken to acquire images of an open cluster and a couple of comets     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  5.5°C (minimum)  - CCD Temperature:  -15°C (58% av. power) - Notes from 2018-11-07 >>
