Not a surprise at all, but we now have a rotating, opening and closing dome! Next steps are to putty in the weather seal along edges, and it will be complete. The interior of the building is getting walls and paint soon. Lighting and network cabling come next followed by the installation of the telescope by end of January! Stay tuned!
A wide angle look at the dome interior with the lower shutter open.
Exterior view with the lower shutter open and the dome rotated to point north.
All three of the observatory’s domes visible for comparison.
Below: Two short movies of the dome shutter being opened. This is a two-part process with the top shutter opened first followed by the lower shutter which tilts out. The top shutter’s lower edge overlaps the bottom shutter thus preventing weather from getting inside.
This has been an exciting couple of weeks. As we have seen our first frost of the season (no snow just yet!), we have been putting up the frame and the structure of the building. Click on images for full size.
The corners of the building have been placed and the first wall frame goes up.
Work on the wall frames continues. Soon after this they will be sheathed with plywood.
The four walls are up, and the roof’s lower layers have been installed. There is also a ring for the dome.
The entrance to the observatory. Note the walls inside have yet to receive their plywood, and the floor needs to have concrete poured.
A view of the dome base framework from the rooftop. Imagine a large telescope on the pier with a 16′ dome surrounding it. The roof has a slight pitch to allow water and snow to run off to the north.
Another view from the roof. Where is that dome? Here it is! It’s the bundle of materials on the pallet. Some assembly is required. The black mats are covering what will be the walkway to the building.
Construction is well on its way. The pier being poured and the concrete now setting, the various braces have been removed allowing for a clear view of the structure’s foundation.
