Progress on Telescope Installation

We worked to finish as much as we can at Site #2 today. We fixed an unhappy servo motor on the Dec axis (motor encoder was mounted a bit off center), and got the dome home switch working with the TCS software.

We finished the modifications on the camera mounting adapter, and we will try...

Back at SPM to Finish Telescope Installation

I arrived at SPM yesterday afternoon with Mark Kelley from DFM Engineering to start wrapping up the work on the telescope installation. We are starting on fixing the wiring and other electrical issues, and we will finish up fixing the HA backlash problems at Sites #1 and #3.

So far...

Dome Shutter Fixed at Site #3

We fixed the dome shutter problem at Site #3 today. We had to replace one of the rollers and grind a bit off of the roller mounting bracket. We also pulled the tracks closer together at the bottom of the range of motion for the upper shutter. The whole process only took about 2 hours.

We swapped them today and finished early this aft...

First primary mirror and mirror cell installed

Today we installed the primary mirror on the first telescope, at Site #1. The operation went very well, with no problems to report. We worked on the installation of the secondary mirror this afternoon as well, but we found a couple holes in the truss ring that needed to be countersunk, so we will...

Installation of first primary mirror into mirror cell

We started installation of the primary mirror into the mirror cell at Site #1 this morning. We got the mirror centered and leveled relative to the mirror cell, then at the end of the day we were able to glue the blocks onto the side of the mirror which are attached to the radial support arms. We...
