People

Onkar, Roy, joined later by Gabriel (for 30 mins), then Matt, Natalie, Katie. Roy left at 2145

Spaces Occupied

433C, 401, Dome

Goals

  1. Open things up
  2. Close them down
  3. Observe stars, blazars, and maybe Mars
  4. Observe ZTF

Log

  1. Followed opening procedure
  2. Connected cameras to scope
    1. planetary on axis
    2. deep sky on finderscope
  3. pointing at Capella
  4. Attempting to focus
    1. Attempted to measure Seeing via FWHM reported by SharpCap in pixels.
    2. Calculated 25'' for planetary camera (13.8 pix average for best FWHM measure)
      1. 2.4um/pix → 6500 mm focus for DFM Scope → pixScale/focalLength*206.265
    3. Couldn't accurately determine focal length of finderscope, so couldn't figure angular resolution of detector easily
  5. It was very clear that the tracking is off with on-axis camera
  6. Moved to ZTF, similar to last time: just fuzzy
  7. Took some saves with finderscope (darn: saved as PNGs)
    1. Onkar fixed this. Roy only made it worse
    2. onkar update: pixel resolution is still off idk how to fix it but still usable
  8. Moved to a variety of blazar objects:
    1. m87 - on Eastern horizon. Will rise through haze after clouds arrive
    2. 3c 273 - in virgo, below the horizon
    3. ngc 1275 - Sparse
    4. ngc 3862 - east, lots of light pollution in that direction
    5. m77 - Galaxy, tried to get good exposures
      1. unsuccessful, not sure if I was looking at it
    6. m42 - great orion nebula, beautiful as always
    7. ngc 1432 - pleiades maia nebula, purdy
  9. SHUTTING DOWN

ToDo

  1. Second security camera needs to be installed near dome encoder.
  2. Get static IP for network switch
  3. Roy: Bring side table in for control room

Notes

  1. Tracking is bad. – We observed Capella move upwards out of the frame over the course of minutes while using the on-axis planetary CMOS.
  2. Dome shutter woes – Onkar Rekhi 
  3. Need to ensure data is saved in FITS files. PNGs are dumb. - Roy

Weather

NOAA: 30% sky cover

WU: 0%-10% sky cover

CSC: Poor transparency, Poor Seeing

Data

SharpCap Standard folder on DC and also on googleDrive
