I recently had the pleasure of working on my mirror under the tutelage of Bob Goff, the Master Optician at AXE in Tuscon. He gave me the following letter to distribute among the ATM's and Amateur Astronomy Community. This letteer has been sent to Sky and Telescope, Astronomy, and other Astronomy publications. But, you will probably see it here first! I'll relate my mirror making experience in another posting. Jim

Re: Setting international standards for amateur astronomical telescope systems
Dear Telescope Enthusiast:
The International Standards Organization (ISO) is establishing international standards for the optics industry. The American National Standards Institute, the National Association of Photographic Manufacturers, and the Imaging Technology Committee 11-Optics and Optical Instruments (ANSI/NAPM IT.11) have appointed me the United States leader to the ISO Technical Committee 172 (Optics), Subcommittee 4 (Telescopic Systems), Working Group 3 (Amateur Astronomical Telescopes), referred to as ISO/TC 172/SC4/WG3. Countries represented on SC4 are Austria, China, Germany, Japan, Russia, United Kingdom, and USA. The Japanese are conveners of WG3 and have responsibility for overall administration of this work.
My role is to formulate the US input to the convener and to see that drafts of pertinent documents are circulated to the US members of this working group. It is also my function to represent USA amateur telescope manufacturers' and users' interests at the international level to set standards of performance, test methods, and general terms and definitions that are typical for all amateur astronomical telescopic systems.
Two recent meetings held relative to this effort were the ISO/TC 172/SC4 Moscow meeting held June 28 to July 1, 1994, and the ISO/TC 172 Plenary, attended by more than 270 experts from all over the world, held in Tucson, June 5-17, 1995. Enclosed is the Strategic Policy Statement drafted at this meeting for the ISO/TC 172/SC4 (Telescopic Systems). The committee will be developing standards to be provided in a document to the user at the time of telescopic purchase.
Any users of amateur telescope systems interested in providing input to this process can contact me directly. I will be happy to communicate their suggestions to this committee for setting the optical standards for these products . Suggestions must be provided to me in a written format suitable for submission to the international working group.
Sincerely,
Robert F. Goff Owner & Master Optician
