In my 20s and 30s I built two observatories and two observatory telescope mounts (among a number of smaller portable telescopes and mounts). The logistics of handling parts too large and heavy for one person to pick up are interesting. The photos in this gallery will give you a feel for what those projects were like.
01. The first observatory was 5/8 of a sphere and was 13 feet in diameter. The whole building rotates except the floor and the telescope mounting.
