Session Aims & Highlights (2021-02-22)

Main aims

  1. AstroMain.  Test features and fixes added in AstroMain 3.36 software, and crucially test stability and absence of UI lockups
  2. ObsCam. Conduct first live test of new AstroObsCam software for capturing webcam pictures of the telescope & interior of the observatory during operation including AstroAllSky-AstroObsCam communication and picture upload & display on current session webpage.
  3. Targets. Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by conditions.
