Log

  1. Removed detectors
    1. Removed ASI 2600 from finder scope
    2. Removed ASI 432 from main scope
    3. Attached to DC in CR
  2. Started with 2600
    1. Placed in dark box on chair and covered box with jacket
    2. Connected to SharpCap and set cooler target temp to -10 (idk if this is relative measure or C or F or K …)
    3. Set SC Gain to 0
    4. Set SC Brightness to 0
    5. Mono16 FITS
    6. Took sample frame to examine header.
      1. CCD-TEMP is at -7.3C
      2. Going to wait a few more minutes and repeat to see if it decreases
      3. CCD-TEMP did get to -10C. Adjusting understanding of TargetTemp in SC (it seems to be degrees C)
    7. With gain of 0, brightness of 0, target temp at 10C
      1. Took 10 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms
