Log

  1. Normal startup procedure, mirror doors opened without issue
  2. Took sky flats at 1522 in all five filters. Saved in Z:ObservatoryData/NINA/2023-12-12
    1. Removed flats from 2023-12-11, since the IR lamp was on in the dome
  3. Pointed at Deneb and set object position approx 1630
  4. Calibrated phd2 on Deneb
  5. Went from Deneb to HD 198478 for seeing estimations
    1. SharpCap Measured 5.0 +- 0.1
    2. PHD2 Measured 4.5“. HFD 6.5
    3. Three frames collected and stored in Z:ObservatoryData/SharpCap/2023-12-12
