Hi,
http://www.hubbleoptics.com/HNA.html
Has anyone heard of or read a review of these hyperbolic mirrors and correctors?
If you believe the sales pitch sounds like a dream come true " It will provide more than 50mm of fully corrected flat field."
The complete kit includes a hyperbolic mirror, high quality secondary with a matching 3.5in corrector.
The pricing is confuisng however, it gives the prices for the mirrors and a price for the corrector but doesn't mention if the secondary comes with it. I was interested in their 14in F4.2, manageable focal length at 1494mm.
Regards
Bill
