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 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms
      2. Checked CCD-TEMP field of final frame between each set, only proceeded when reported at between -10C and -7C
      3. Lul SharpCap reports real-time temperature and target at bottom of GUI
    8. With gain of 0, brightness of 0, target temp at 0C
      1. Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms
    9. With gain of 1, brightness of 0, target temp at -10C
      1. Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms
    10. With gain of 1, brightness of 0, target temp at 0C
      1. Opened box a bit bc cooler was struggling to keep temperature
      2. Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms
    11. With gain of 5, brightness of 0, target temp at 0C
      1. Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms
    12. With gain of 10, brightness of 0, target temp at 0C
      1. Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms
    13. With gain of 50, brightness of 0, target temp at 0C
      1. Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms, 50 000ms
    14. With gain of 100, brightness of 0, target temp at 0C
      1. Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms
    15. With gain of 150, brightness of 0, target temp at 0C
      1. Took 5 frames each at 0.032ms, 0.1ms, 0.5ms, 1ms, 5ms, 10ms, 50ms, 100ms, 500ms, 1000ms, 5000ms, 10 000ms
  1. This took SO LONG. I need to figure out to use the sequencer in sharpCap. I saw that I could likely use the Deep Sky planner, but it only let tenths of a second stand for exposure times. This makes sense for DSO sequencing. There may be a way to get around it. ALSO I may not need this ridiculously short exposure time to suss-out the GAIN and BIAS levels.
  1. Ran the sequencer for the ASI 432 with gain levels 0 and 25, but only the following exposure times
    1. 0.1,0.5,1,2,3,4,5,7.5,10,15,20
    2. Saved this as calibrationTestSequence in SharpCap Folder in Z Drive.
  2. Synced Data to normal gDrive folder
  3. LEFT ASI2600 AND ASI432 in control room
  4. These will obv need to be reattached.
