Session Aims & Highlights (2021-04-01)

Main aims

  1. AstroMain  Test out v 3.38.12. Check that version is able to successfully retrieve targets associated with the nights Observing Plan or hangs like the earlier 3.38.11 version.
  2. Targets. Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by conditions
