Telescope Making No. 40 (Spring 1990)

The Spring 1990 issue of Telescope Making — “the magazine for, by, and about telescope makers” — features the following articles:


-“A Model of Herschel’s Uranus Telescope,” by Ferdinand Miller, Jr.


-“Central Obstructions and the Airy Disk,” by Richard Berry


-“Building a 4-Inch Plywood Refractor,” by David Cartwright


-“Split Roll-Off-Roof Observatories,” by Gregg D. Thompson


-“Robert Edward Cox, Telescope Nut,” by the readers of Telescope Making


-“The 1990 Winter Star Party,” by Richard Berry


Telescope Making debuted in 1978 in response to Astronomy magazine readers’ demand for more information about how to build telescopes. In the premiere issue, Editor Richard Berry explained the magazine’s mission: “We see TM as a magazine that will help people share their ideas and learn from each other. ... You, and the telescopes you build, are its subject.” Telescope Making ran quarterly until 1992.
