Assorted Photographs from Construction of the Doc G Observatory
The photos show some details of the construction. The pier and the deck posts were set in concrete after careful alignment with each other and with true North. North being to the rear part of the deck. The bottom portion, which included the wheel structure, was constructed next and put in place. The rail is mounted on solid twin 2 by 12 beams which are 20 feet long. There is a pair of beams on each side of the deck which supports the entire structure. Eight posts set in concrete go down 5 feet into bed rock. The deck is extremely solid and the building very heavy. It still rolls easily on eight "V" grooved wheels along the steel tracks. Then rolled back, the telescope easily sees the area of the sky around polaris. North is to the left. In the background is the conventional observatory building housing the C-11.
The building was constructed in situ on top of the base assembly.
Details of the heavy duty rails and roller assembly can be seen in several
of the photos. The internal section was installed as a wind break
and to hold shelves, charts, the computer and assorted accessories.
When the main doors are closed the building is very weatherproof, as it
has to be in Wisconsin's harsh climate. Never-the-less the building
is easily opened, rolled back and the telescope ready to go in less than
5 minutes.
