Fill Out Your Library of Willmann-Bell Books! pThe floor is cut out to accommodate the telescope pier. A removable section seals the slot tight against intrusive creatures. The section to the right is a brace that goes under the sill. pThe building rests on a framework of crisscrossed 2″ × 10″ lumber. See all available titles: shopatsky.com/collections/willmann-bell as working out of the back of a car. Plus, there's room for Laird and his guests to step inside and warm up on cold nights. Since the floor moves away with the building, Laird laid down an observing platform of concrete pavers, then covered it with indoor-outdoor carpet for added comfort. His California climate is dry enough that he doesn't need to remove the carpet between observing sessions, although that would be easy enough to do in wetter climes. During the day, the north side of the building is perfectly usable space in his friend Manny's yard. Two rails mark the wheels' path, but there's no overhead structure to contend with and no posts to get in the way of lawnmowers or other encroachments. By day it's just a storage shed in the yard, but by night it's a fully functional and very convenient observatory.
