Session Aims & Highlights (2021-06-05)

Main aims

  1. AstroMain.  Try out AstroMain 3.40.4, following further refactoring of code connected with plate-solving.  Check out fixes and enhancements. Check for any new issues / introduced bugs.
  2. Guiding.  Collect information to understand the impact of focuser movements & associated change in weight distribution on guiding
  3. Targets. Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by time & conditions
