Other Projects

The fascination with optics has led to designing and building for customers unusual devices such as the phasematrope and the kaleidoscope.  Photographers and artists regularly contact me with questions about how to use a simple camera obscura to enhance their pictures and visual displays to explore the world around them.

Fixed Eyepiece Telescopes

Soon after moving to the Tehachapi Mountains at 6500 ft. altitude, I realized my lifelong dream of building a fixed eyepiece telescope for observing in a warm room. Earlier telescope makers, such as Russell W. Porter and John H. Hindle led the way with their designs and I was able to learn from their valuable experiences.
