Problem(s) Encountered:

Noticed two technical issues: N-S guiding on telescope can be jumpy and inconsistent. Stars tend to be smeared out along N-S axis, regardless of focus. Did not greatly affect observations.

The main shutter makes an unhealthy rattling noise when opening, during the very last moments before it is fully opened.

Solutions:

If the N-S issue is truly with the guider, then adjusting aggressiveness etc might have a positive influence.  I’m wondering though if this is more likely caused by the intermittent nodding inherent to the TCS upgrade years ago.

The track for the dome shutter has been lubricated where it can be reached.  Full lubrication will be performed when we have use of the NOAO manlift.  In the meantime, what has been done should help minimize the rattling upon opening.
