Fig 1.40 The “Clapp Trapp” was easily folded up into a 14-inch-high stack of folded panels
measuring 2 by 4 feet and weighed only 125 pounds. It fit into most larger vehicle trunks.

Fig 1.41 The “Clapp Trapp” walls were hinged in pairs allowing them to be self-supporting
during assembly. They hooked together to form an octagonal structure which supported
the roof. Note the smart use of “pouches” to hold accessories on the inside walls.

Fig 2.5 Installation of tile drains will lower the water table around your site. Carefully
directed away to a lower spot on your lot, they will transfer the moisture to a less
critical area.

Fig 2.8 A typical suburban lot complete with garage showing the critical zoning
provisions
which change for each zone. Note the multitude of factors which direct the observatory
location: – side-yard minimums, rear yard minimum, proximity to tile field, well, trees, and
the requirement for a northern alignment. Normally the rolled-off roof should go in a
northerly direction.

Fig 3.3 Orientation of the observatory with roof rolled off northward is the best
arrangement with no southern obstruction by the roof gable. Normally, except in very
southern latitudes Polaris is still high enough above the roof gable to be imaged and allow
for polar-aligning the telescope. In this set-up the garage, large trees and rear-yard setback limit possible locations, but if the garage roof is low enough a fair western view is
still possible. The Southern sky is completely accessible which is a priority.

Fig 4.1 Calculating Pier height. A typical Schmidt-Cassegrain telescope with fork mount
is shown in horizontal position. This is the maximum height of the pier in this case for
the instrument to clear the rolling roof.

Fig 4.3 Detail of finished metal pier top on its concrete foundation showing electrical
conduit, electrical outlets, and bolts anchoring the metal top to the concrete footing
underneath. Normally the metal pier top should begin about 2 inches above your

observatory floor. For comparison, the faint image of a foundation Sono-tube footing is
aligned at its exact height illustrating where floor joists would sit in the bracket on the
top. From this you can visualize that the steel pier base rests about 2” above the finished
floor surface.
