Summary

LFBG

03:00 Preset ACTIVE to BS9152, collimate

03:20 Preset GUIDE to BS9152 so can collect pupil data

03:34 pupil_collect: pupil_03:34:31.log. About a 2 pixel diameter wobble, so no change needed
  • Note, for each offset in rotation of 60 degrees the guider had to pull the guide star back to the hotspot. This tells use the default on-axis position of the guide probe is not on the rotator axis.
