Session Aims & Highlights (2023-01-28)

Main aims

  1. Targets.  Acquire images of a selection of variable stars, nearby stars, comets & deep sky targets as allowed by sky conditions.
  2. Secondary Scope Imaging/Stacking.  Continue test out of secondary scope imaging with automated in-session stacking of ZWO 178MC frames using and AstroMain's StackCam2Frames() routine, Siril-cli and a Siril script (OSC_stackframes.ssf).
