Session Aims & Highlights (2022-09-27)

Main aims

  1. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by time & twilight conditions.
  2. AstroSuite Programs.  Check out new versions of AstroMain, AstroGuard, AstroVOE, AstroAllSky, AstroWeather which have all ungone revisions associated with ongoing conversion of date variables and record timestamps  from Local to UT kind . Check for all issues.

Night Sky Summary Plot
Top axis: Sky Brightness at Zenith (in ADU/s)
Lefthand axis: Local Time (hh LT). Righthand axis: Sun Altitude (degs)

Various gaps between 19:30 and 00:45 (some gaps are obvious, some only apparent because of gaps in
 Sun Alt labelling,  normaly 2 deg intervals). Issue was due to a bug in a newly introduced routine in AstroAllSky 3.17.
This was fixed in-session (3.17.1) and the new version ran successfully from 00:50 onwards
