Equipment Failure

ROAp stars in open clusters. The camera temperature read -1000 C intermittently and at the start of the night the temp was -103 C and not at the set point of -110 C. Six hours later, the CCD temp read -108 C. Thee cooler appeared to have difficulty reaching the set point. The big issue was that the secondary mirror did not appear to move in response to commanded focus changes. At the start of the night, there were double images. A change of focus of 200 units produced more round images. We attempted to adjust the mirror position for better focus but the images kept getting bigger, no matter whether we jogged the mirror up or down. Eventually, we arrived at large donuts. We did a full system recycle including recycling the power on to the telescope, the telescope computer and ACE control cabinet. Though we did not cycle the camera control computer. This appeared to fix the camera temperature readout issue. After the system restart, the indicated focus position was "1'. We commanded the focus to zero and then back to the nominal focus position in the "Go to focus" box but the images was the same large donut. Focus jogs as large as 3000 units failed to change the size of the image. The encoder reflected the commanded jog but the image size did not change. The secondary mirror appears to be stuck.

EB and novae. No major issues, though you still have to send tele to the first target of the night 2x before it will move. I noted in Discord that both pc's were showing anti-virus messages about publicly visible IPs and tracking cookies along with updates that may require pc reboots; Peter said he'd look into it.

No major issues, But guide camera kept disconnecting early, Focus required driving to Zero couple of times before it would respond.

Wind

T Cor Bor and EB. Focus was a huge problem after finding a 3" FWHM early on but after a few hours it looked bad and adjustments sent me spiraling down from 160,000 to 100,000 with no reasonable seeing FWHM to be found, but I may have also been fighting seeing issues due to wind, which ultimately shut the mountain down a few hours early.

Spectra of WR Stars - Only issue was several instances of QHY guide camera hanging during long tracking sequences. Restarts quickly, but a couple of long exposure images lost.
