swift-telescopes: Swfit Telescope List

This is a List dedicated to the study of the the Swift Models 831, 838, 839, and 818 telescopes in the early 1960's, and the various accessories which were sold with these telescopes at that time. The List will be primarily devoted to a discussion of the optical and mechanical characteristics of this equipment and of the care necessary for the proper use and maintenance of these items. There will be some discussion of general astronomical usage but this will be in relation to the design amd manufacture of these astronomical instruments.
