Spaces Occupied

PHYS 401, 433C, Dome

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
