Goals

  1. Reattach ASI 432 with necessary adapters/instrumentation
  2. Collect flat field frames in UBVRI, emphasis on BV if time constrained
  3. Run smart histogram tool on four fields in each filter provided by Eileen to find recommended settings
  4. Capture a few dozen light frames of these fields in each filter at recommended settings

Log

  1. There is some issue with slewing to Zenith
    1. What TS6 and DFMTCS report as Zenith is not 'straight-up'
  2. Roy removed from GAM-lite bottom plate ThorLabs LCP01 plate via 4x screws with 5/32 allen key
  3. Roy re-attached ThorLabs instrument rotator with 4x screws with 3/16 allen key
    1. USB cable into remote Icron
    2. Serial cable to ThorLabs controller
    3. Opened Kinesis and attempted to connect – failed
    4. Needed to power cycle through Power Controller (outlet 5)
  4. Roy dusted (with compressed air) the filter wheel and reattached ASI 432 CMOS to filter wheel
    1. Confirmed UBVRI ordering
  5. Roy attached filter wheel/432 assembly to on-axis
  6. Olivia and Roy decided to wait to the end of the night to collect calibration frames
  7. Pointed at Deneb
  8. Using Kinesis, aligned 432 to North-up at $230^\circ$ (set speed to $5^\circ/s$)
  9. Moved to NGC 7790
  10. Moved to SA20
  11. Moved to PG2213
  12. Moved to 110 field – failed. Too low? DFM TCS reported target out of range … but it sat at +24 altitude
    1. OH WELL
  13. Hatch door piston fell off
    1. That sounds bad, but the piston unscrewed itself and wouldn't hold the hatch up
    2. Olivia and Roy fixed it :)
  14. Pointed main scope at dome flat fielder (see image) for flats
  15. Slewed to Zenith with DFM TCS
  16. Removed from filter wheel and placed in box, turned out all lights and took darks and biases
  17. Stowed 432 and filter wheel in 433C
  18. Normal shutdown procedure

ToDo

Extract magnitudes

  1. No issues with mirror doors
