Guide probe motion failure
Sunday, March 14, 2021 6:10 AM
The guider focus did not budge when commanded. The guider does surprisingly well on not-too-grossly out-of-focus images and no time was lost.
That problem had been intermittently occurring for some time prior to this. Finally had a day off-sky where we could open up the bottom of the MIS for closer inspection. Initially, all worked as expected. Guide probe motor mic travel, optical cart travel, etc. But a little shaking of the wires and power to the motor mic would interrupt. A little more shaking and one wire completely fell apart. Managed to splice in a new connection. All soldered and heat shrunk. Everything seems to be working again. Hopefully it stays that way.
