Objects Session Notes
NGC 6802 - Open Cluster NGC 6830 - Open Cluster NGC 7086 - Open Cluster NGC 7062 - Open Cluster Astrometric & Photometric Monitoring - SS Cyg (dwarf nova)
- BL Lac (blazar)
- RX And, Z And, R CrB, DY Per, RU Peg, FU Ori, RR Tau, KR Aur (variables)
- Barnards Star, HH And (Nearby Stars)
- 61 Cyg attempt (failed link/cloud)
- Session in two parts
Part 1 -Late evening
Part 2 -Morning (PreDawn)
Late evening session was prematurely terminated due to developing cloud.
Cloud was found to have cleared by 3.30am and allowed a Pre-Dawn session .- Ambient Temperature 11-12degC (late evening), 7-9 deg C (pre-dawn) - CCD operation of -20 degC
(at 81% average cooling).- main objective was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - opportunity take to acquire images of selected open clusters from Herschell 400 Catalog -
