CFF Telescopes to Create Limited Edition Binoscopes Based on 135mm F6.7 Triplet Refractors

CFF Telescopes has announced that it will produce a limited edition binoscope based on its 135mm f6.7 Triplet Refractor design.

The binoscopes are built around two of these optical tube assemblies and shortened to accommodate a 3-inch fusion image system. By using the maximum practical aperture for the focusers and an EMS system (Erecting Mirror System invented by Tatsuro Matsumoto of Japan), the bino’s will allow using 2-inch eyepieces without any vignetting of the light cone.

They will have the practical light gathering power of a 190-mm unobstructed objective while the use of both eyes in a natural way increases perceived resolution.

There will be 7 custom binoscopes produced. The first unit will be available for delivery in December 2018, with other units following in 2019. The price is 13,990 Euro, which includes a 23% VAT. The none Vat price is 11,374 Euro.
