I assembled this using nothing but hand tools out doors at a camp ground in 1989 at the top of Fremont Peaks.
Built as part of a homemade telescope contest in view of other amateur astronomers without any electricity just hand tools.
It had a few interesting design features. The whole thing could be taken apart with just 1 screw and fit easily in the trunk of my 89 Nissan Sentra.
The main lens adjust was a 2 point system, X & Y allowing for super easy adjustment.
Everything was design to build using only a few cuts and holes drilled including the lens adjuster.
