Giant Eyepieces That Swallow Spacecraft

Giant Eyepieces That Swallow Spacecraft

Al’s talk covers his early telescope making projects, 50-plus years of attending Stellafane (the historic amateur telescope maker’s convention in Vermont), and his Farrand Optical career experiences designing the NASA project-Gemini and Apollo-LEM visual simulators for astronaut training. Al will describe how they work and how, years later, the simulator views inspired him to develop the Nagler eyepiece, whose optical concept was derived from working on complex optical probes used for landing simulation.
