Session Aims & Highlights (2024-11-09)

Main aims

  1. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by sky conditions.
  2. Dome Slews. Collect DeviceHub activity data to understand why dome slewing anomalies are occuring whilst dome is slaved.
  3. Crab Nebula.  Acquire 1x1 binned, 60s exposures of M1 / CM Tau to assess the needs/limitations for the Crab Nebula Pulser Project.
  4. IK Peg. Acquire images of IK Peg, a white dwarf / binary system in Pegasus and around 154 ly from earth.
