Session Notes

M53 - Globular Cluster     NGC 4051 - Spiral Galaxy Variable Stars (photometric monitoring) - CV CMi, U Gem, RZ LMi, CN Ori, CZ Ori, FO Ori, FU Ori, DY per, GK Per, ER UMa - RX And, U And, W Wand, Z And attempts failed (due to dew) Nearby Stars (astrometric monitoring) - DX Cnc, Groombridge 34

- Evening session (2.9 hrs duration).  Clear and calm conditions, Dew, Moonlight - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Main objective of the session was to take images of NGC 4051 and M53 with my 12" LX200 in NE Scotland to compare with those submitted for acquisition by the robotic 2m Liverpool Telescope in La Palma - Ambient Temperature:  1.0°C minimum - CCD operation -30°C (at 75% average cooling).   - -
