History

The Brandon lens design was invented by Chester Brandon.  Don Vernon Yeier founded VERNONscope in 1958.  In 1966, Don purchased the designs from Chester Brandon and built Brandon eyepieces and other optical accessories in Candor, NY.  Don retired in 2013 and sold the company. The Brandon eyepieces are still manufactured in the USA in NC under the company name of Vernonscope LLC using the same perfected processes.

Vernonscope also makes threaded eyepieces for Questar Corporation.

You can purchase these special eyepieces from Questar.
