Session Aims & Highlights (2019-02-07)

Main aims

  1. Undertake Deep Sky, Variable Star and Nearby Star imaging
    (plan was to take advantage of clear evening skies before forecast clouds rolled at 22:00 -23:00 hrs)
  2. Monitor Observatory for incidences of unexpected closures of the dome's shutter
    (this has been a problem in recent sessions and particularly during session S647 three nights ago)
  3. Test updated /new routines in AstroMain 3.8.8, if time allowed
    (this includes new focus logging and Sky Survey focusing)

Dark Frames,  -20°C

44 dark frame sets were acquired with ST-10XME Camera at CCD temperature of -20°C in order to build master dark frames for reduction of raw images from Session S659, 2019-02-05
