Good news. The observatory is just about done. I mounted the telescope today. Photo is below. Ignore the wires -- still have to tidy up.
Bad news. The motor control board in my CGE Pro mount is shot. Was on the phone all day with Celestron. So one day after assembling everything for the first time, I have to take it apart and ship the mount back. (It worked OK a couple of months ago during tests but started to go crazy about 2-3 weeks ago.)
It has been 15 months to this point. Now we have to wait another 6-8 weeks.
