I'll leave the various electronics on overnight so Haosheng can work on it. I'll take the dome out of computer control after I close it, to be safe.

But I did figure out how the circuitry works and exactly where to mount the new switches and made some progress removing uneeded circuitry and wiring and making the new mounts. It should go fairly fast and easy now, I'll get dark shutter hooked up and tested on Saturday, and if the weather permits I should be able to do the ND filter too. Right now the dark shutter isn't functional. On the spar, both the ND filter and the dark shutter mechanism cables are unplugged.
