Log

  1. Took multiple attempts to open the mirror doors
  2. Pointing to Deneb and Saturn
  3. Slewed and captured HD_213306, HIP_117690, HD_236349, HIP_8312
  4. Recaptured the above objects again
  5. Slewed and captured HIP_278195, HD_31913
  6. Recaptured HD_213306, HIP_117690, HD_236349, HIP_8312, HD_278195, HD_31913
  7. Recaptured HD_213306, HIP_117690

2100 - Percy arrived 2117 - 4th capture of HD_236349 2136 - 4th capture of HIP_8312

  • Noticed clouds rolling in mid-capture, around 2140
  • This capture is unusable due to cloud interference

2200 - Nick arrived

  • Received the thumbs up from Brayden to wait the clouds out until 2230

2230 - Still very cloudy, closing the dome to begin taking flat frames 2243 - Flat frames, 35s 2255 - Closed the dome up for darks 2300 - North and south mirror doors stuck, south mirror door went down after tilting the telescope north

  • waiting until 2310 to see if the north mirror door will close to gravity as well - otherwise we will have to
  • de-thermalize the dome to thaw the motors

2310 - de-thermalized the dome and the north mirror door went down after 10 mins of thawing 2322 - taking darks
