The new JMI focuser wouldn’t screw onto the back of the orange 8″ Celestron, so the focuser was installed on the black 8″ Celestron. The Mallincam, 10mm spacer, and MFR5 focal reducer were then added and using the new mounting plate, the black 8″ Celestron was piggybacked onto, and then aligned to the 24″. The focuser was checked for proper electrical and manual operation. It was noted that the black Celestron OTA is dented in a couple of places. The orange Celestron was installed on the CG5 mount. The 24″ telescope was not rebalanced at this time, as it appeared to operate properly through the areas of the sky (east through the south to northwest) we were viewing in.

I swapped out the GX280 Tatla Lake computer with the spare GX280 I had brought along. A close inspection found swollen caps, so they’ll have to be changed out.

Replaced the fan in the Mile 108 camera assembly and substituted it for the Tatla camera assembly that I brought home. Both systems are operating properly although the Tatla image shows scaffolding to the south placed by the roofers who are replacing all the roofing material at the Tatla School. I had to work around them to swap out the camera. They’ll be done in 2 weeks.

I think one maintenance trip a year will be enough. Both computers were clean, the fans were still operating properly, and the domes were reasonably clean.
