I spent all afternoon at the Cradle of Aviation in Garden City, at their Astronomy Day. I brought with me one of my home made telescopes, and a telescope mirror, and this glass and wood "telescope." I built this device to show to some middle school children when I gave a talk one time. It is a wonderful demonstrator for kids - it includes the glass lens to the right, in an open frame, and a telescope eyepiece on the left. Viewers wondering how a telescope works can see that there is nothing else in the tube - just a lens and an eyepiece. This gentleman who stopped at my table was fascinated by it, first photographing it sitting on the table, and then he picked it up and spent quite a while looking through it. I love to see his concentration, and how his fingers are gently holding the device.
