Wrapped and dome installed.

Window is in.

We had another rare sunny and nice October weekend this week. Temps in the mid-70s.  Again we did more work on the observatory, getting it closer to being completed - at least on the outside.
Window was installed after work last week in the brief daylight we have left in the early evening.
Yesterday we got the weatherproofing tar paper on the walls and got the dome installed.

Take the tarp off, and get dumped on!
It was a short and heavy shower.

The dome is just put up finger-tight right now, I'll need to get a few more nuts and bolts of the stainless-steel type, and a few springs that were rusting and leaving ugly stains on the dome.
The dome flange needed a little coaxing (and yes, a little cussing - that's a requirement with anything with astronomy) to get it all lined up on the flange.

With some tweaking and nudging, it fit on the square
support pretty well. 

Ring around the dome, and wrapped walls

Half dome installed. 

Once the flange was up, the dome ring with the roller wheels was next.   This was easy, but it always takes a lot of tweaking to get the rolling ring to line up and not stick in certain parts.  The dome halves went in easy enough, but will require some adjustments as expected to get a good smooth rotation.   Always a pain...I think I  mentioned that already?
I spent all of Saturday working on the dome install and other things with Traci's help.  She did all the tar paper while I was up on top.
Our shortening days (Sunset around 6:45) is really making this a race before darkness to get done.  As seen in the last photo, darkness doesn't stop me from the last few adjustments!

At least I'm on a short ladder this time.  The last observatory
I was balanced dangerously on top of the "don't step here" step
on the step ladder.   

Just one more attachment do to before putting tools away for
the night!
