Amateur telescope making

Cox built his first telescope, a 6-inch reflector

A reflecting telescope is an optical telescope which uses a single or combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century as an alternative to the refracting telescope which, at that time, was a design that suffered from...

, at age 16 and four years later had completed a 10-inch reflector as well. With Lou Lojas, Ed Hanna and Carl Groswendt, he founded the Amateur Telescope Makers of New York which became the Optical Division of the New York Amateur Astronomers Association in 1937. The Optical Division conducted evening telescope making classes in the basement of New York's Hayden Planetarium

When Earle Brown stepped down as conductor of Sky and Telescopes "Gleanings for ATMs" column in 1956, Cox took over the department, which he ran until December 1977, for a total of 254 installments. The columns contained practical telescope making ideas, shop techniques, and wisdom drawn from his professional career as an optical engineer. Some of the early columns were later collected into a book, Gleanings Bulletin C.

, Cox wrote:

It is generally conceded that anyone who mounts a mirror or lens as a telescope for viewing celestial objects has become a telescope "nut" regardless of how the optics were obtained. There is only one important requirement - that the optics be of first quality, capable of giving satisfactory views of the moon, the sun, double stars, cluster, nebulae, and the planets.

Cox maintained a voluminous correspondence with both amateurs and professionals throughout his life. He was a frequent and sought-after speaker at meetings of amateur astronomers.
