Objects Session Notes
M29 - Open Cluster M34 - Open Cluster V1251 Cyg - variable star (Type UG) Astrometric & Photometric Monitoring - SS Cyg (dwarf nova)
- U And, W And, U Her, SS Her (mira variables)
- BL Lac (blazar)
- GP And, RX And, Z And, Eps Aur, Zet Aur, R CrB, Cyg_V1251, CI Cyg, RU Peg, CY Lyr, HX Peg, RU Peg, Per DY, Per GK, Sge FG, Sge U, Sge V (variables)
- Barnard's Star (Nearby Stars)
- WZ Sge attempt (failed due to poor sky conditions)
- Evening session (6.9 hrs), operated largely under automated control with remote monitoring. - Ambient Temperature 2 - 3 degC dropping to 0.5 degC (minimum), then rising to 2 degC - CCD operation of -20 degC
(at 57% average cooling).- main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - opportunity taken to acquire mosoic of two messier open clusters M29 & M34
