On the night of July 25/26, 2022, under fair conditions, RIT physics major Myrra Small and I made small adjustments to the collimation of the Celestron 14-inch telescope. I also checked to see if we'd be able to see the UT Aug 9 occultation by Quaoar.
Using the integrating video camera on the Celestron 14-inch telescope -- the repaired Dec motor now works just fine! -- we examined the out-of-focus appearance of the star Arcturus. Initially, we saw only a small mis-centering of the central dark shadow. I made a small adjustment to one collimation screw which put the shadow very close to the center, then a smaller adjustment to a second screw ... and it looked pretty good. We stopped at that point. I suspect our changes won't improve the image quality very much, but it can't hurt.
I also used the Meade LX200 12-inch telescope in the dome to point to a very particular position in the sky. As described in this posting on the IOTAoccultations group, on UT Aug 9, the Trans-Neptunian Object Quaoar will pass in front of a star for observers across a wide swathe of North America. Because we are near the eastern edge of the track, the event is poorly placed for us: it will occur at azimuth 239 degrees, altitude 9 degrees. Very low in the sky!
I determined that the star HD 112304 would appear at nearly this same location in the sky at 10:00 PM tonight. So, at about 9:45 PM, we star-hopped from Spica to this location to see if the star was visible above the trees. Alas, it was not.
No need to try observing the Quaoar event!
