Williams optics ZS66SD Patriot edition

Collectors item? fashion accessory? guide scope?

Was $450 now $350 plus postage

This fun and funky and all round decent baby APO is one of 100 made in 2006 and is one of the 50 marked "United States of America". It is in used but not abused order with some cosmetic blemishes as photographed, but otherwise a cracking little instrument that was only really pressed into service to help feed solar images to NASA for their 2012 eclipse broadcast! https://www.smh.com.au/technology/so...113-299ka.html

Also included is a 2" back. I've dropped the 2"-1.5" part at sometime, but the actual barrel is pristine.
