Session Aims & Highlights (2025-07-07)

Main aims

  1. CCD Camera. Test if major CCD Camera issues during Last Session have been resolved or not
  2. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by sky conditions and the short summer night.

Top axis: Sky Brightness at Zenith (in ADU/s)
Lefthand axis: Local Time (hh LT). Righthand axis: Sun Altitude (degs)
Note:  The NorthCam Star Count line is unreliable and should be ignored
(The AstroNorthCam 'Find' Star method is producing many false positives from clouds)
