6" 1/10wave aluminised flat.
This is a quality 6" 1/10 wave aluminised flat in BK7. 1" thick made by the late Gary Nankivell, (well know optician)[Google for background and experience]. Coating is excellent. Ideal as a test flat, or for folded optics Newtonian. Large flats of this quality are hard to come by.
Asking US$400. Plus post. Payment by Paypal.
