Sub f/4 PrimaryMirrors

Recently I made a 20" f/3.95 Fused Silica (Quartz) primary mirror for Randy Cunningham and Alan Poppenhagen at AstroSystems, Inc. http://www.astrosystems.biz . They will be offering this size in a new
AstroSystems SFL TeleKit (a telescope for customer assembly). Visit
their web site and check it out.

My f/3.95 primaries are guaranteed to be fully corrected to the edge.
Painstakingly figured & tested by both auto collimation-null testing and quality verified by interferometry. Your 100% satisfaction is guaranteed with my optics, you have my name on it.

These optic sets will make outstanding “short” telescopes or fantastic
imaging optics. Astro-imagers, you already have a healthy investment in a CCD camera and a first rate mount, don’t settle for anything less with your choice of optics.

12.5" f/3.95 x 1.5" thick ............................$1850.00
includes matching 3.1" EDM

14.5" f/3.95 x 1.6" thick ............................$2400.00

20" f/3.95 x 2.0" thick ...............................$5500.00
includes matching 4.0" EDM

22" f/3.95 x 2.0" thick .................................$6900.00
includes matching 4.25" EDM

24" f/3.95 x 2.0" thick ................................$8800.00
includes matching 4.5" EDM

I can do optics as fast as f/3.3, null figured & tested and with interferometric photo(s)!. Please allow me an opportunity to quote you a price on your next "fast" set of optics.

No plate glass here, only Pyrex or better substrates. As an option, Fused Silica (Quartz) is available up to 20" diameter, price upon request.

A deposit is required upon acceptance of order and the balance is due
just prior to shipping. I have reasonable and realistic lead times.

The above prices include elliptical diagonal mirror (EDM) and enhanced aluminum coating. Astro imagers can request a larger diagonal for full CCD chip illumination, price will be slightly higher.
