============================================================================= Astronomical Objective: 12.5 inch diameter mirror F/6, full thickness, (2.13 inches) Fully aluminized, and fully parabolized Pyrex, research grade mirror for sale or trade.
This mirror was tested at better than 1/8 wave accuracy, (P-P wavefront) A tested value of .972 for Sterehl rating. All testing was performed by Optical Wave Labs in California. The original test certificate will be included with the mirror when purchased. The mirror was ground by Optical Wave Labs as well. This is a high quality mirror, that has been finished, tested, and aluminized by a professionals in the United States. If you are going to build a 12.5 inch scope, this is the mirror to use! To purchase this mirror, it would cost you between $1000, and $1500, even locating a full thickness Pyrex blank is hard to do anymore. Asking $800.00. I am no longer interested in Astronomy, (I was going to build a scope out of this mirror), and the mirror is now up for sale, or trade, for radio gear. I will consider any like value trade for this mirror. The mirror is in mint condition, not near mint, but mint condition...Unused, unmounted, and still packed in the original shipping box from the lab that ground it. What have you to trade for it? I will pay shipping/Insurance for the mirror within CONUS, you pay shipping/insurance within CONUS for your item. Looking for amps, rigs, test equipment, etc... What have you? Feel free to offer up any sort of like valued ham radio equipment, or pretty much anything electronic, or science related. ============================================================================= -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info for Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info for MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
