Session Aims & Highlights (2020-10-29)

Main aims -

  1. Cam1 Guiding. Test routines and settings for guiding using LX200/ST10 (main scope, north down images) whilst imaging with TS80/178MC (secondary scope)
  2. Targets.  Acquire images of a selection of deep sky targets
  3. Bug fixes.  Check that bugs discovered in last session in AstroMain 3.31.2 have been fixed, and that recent new features are working ok

Pre-Session Weather Forecast (API data from darksky.net)
Pre-Session Weather forecast was poor in first part of night (65-89% cloud cover with high probability of rain),
but partially clear from 21:00 onwards (dry, light winds and 48 to 51% cloud cover).  Minimum temperature 7°C>

In the event rain some rain around dusk quickly stopped and clear patches developed at around 20:30 and 22:30.
A session was started but conditions rapidly cloud over and they were no further clear patches suitable for observing.
Wind was fairly light and min temperature was .
