Beaver PA, Turret Telescope


This is a mechanical drawing Porter made of my grandfather's 12.5" turret telescope. This telescope was featured in Ingalls' Amateur Astronomy section in Scientific American. I'm not sure of the date, but the drawing is from 1942.

All that's left of the telescope is the mirror. (12.5" f8.8)
