The big Saia freight truck pulled up in front in the early afternoon July 10. The ready-to-assemble (RTA) observatory had arrived on two pallets weighing about 625 pounds each. After struggles getting it off the truck, aided by its very helpful driver, and with unexpected help from a neighbor, we stowed the base wall components in the garage. I moved the dome halves myself to a patio space adjacent to the observatory site where they are to be assembled.

Withering hot weather and a severe summer cold (ironic?) halted progress on the observatory dome assembly for several days. This afternoon, July 14, hoping to dive into the work tomorrow morning, I set up a canopy for sun protection. The portable shade along with a good electric fan ought to help extend the day’s work time until I can’t stand the heat!

At long last, here we go!

It has been a long, and bumpy road but, at long last, our SkyShed POD-S observatory structure is arriving! Delivery is set for tomorrow, July 10, via freight truck. Wrangling the large and heavy parts of the RTA (ready-to-assemble) building from street to site will be challenging but I think / I hope I can manage it. One looming problem: once put together, hoisting the assembled dome to rest upon the round base wall is a task that I’m uncertain how we’ll accomplish — the thing will weigh 350 pounds! I’ll need several strong people to help lift the dome but don’t know where they’ll come from.

In the mean time, I’ve assembled a collection of tools and materials required for the assembly, the building permit is in place, and so we forge ahead.

Following the evaporation of our first observatory deal we revisited our pre-purchase research from two years ago. We quickly settled upon the SkyShed Observatories POD-S Mark IV in this project reset. Today we placed our order and paid for the ready-to-assemble kit.

While we were originally hoping for fiberglass construction, the POD-S is built from double-walled polyethylene — much the same as plastic garden sheds. The material actually provides some advantages over other construction but presents an interesting issue: daytime IR heating. It seems white poly is translucent to infrared light (solar heat rays) which causes the interior to heat up. We chose a light gray color which, while not the classic choice for a dome or observatory, we are told will allow less of interior heating, as it blocks more IR than the white color reflects. This flies in the face of the usual reflective white or metallic silver specified for observatories but those buildings aren’t made of polyethylene.

We don’t have production or delivery schedule information at this time (the order’s brand-new) but there are other things to do such as acquiring a new building permit, pulling electrical wire to the telescope pier site, building a warm/control room in a nearby shed.
