About this product
Model: founder_bos_72
Part Number: BOS72
Founder Optics Bino One Scope
Suitable for both terrestrial and celestial observation.
The Founder Bino One Scope is an innovative design that demonstrates the benefits of using both eyes in a Binoviewer configuration.
Observing with both eyes is a more comfortable observing experience. In particular, the views provided have a three-dimensional appearance. This, together with the greater comfort and reduced eye strain, is most noticeable when observing for long periods.
Extra-low Dispersion glass!
The BOS72 and BOS80 feature an objective lens with an ED glass element to reduce chromatic aberration and enhance contrast.
The BOS72 has a 72mm objective lens with a 432mm focal length (f/6). When used with the supplied 12.5mm eyepieces, magnification is 35x
The BOS80 features an 80mm objective lens with a 500mm focal length (f/6.25). When used with the supplied 12.5mm eyepieces, magnification is 40x
Other 1.25" eyepieces can be used to achieve different magnifications.
Other features include tactile rubber armour, a super-smooth internal focus mechanism, a Vixen-type Dovetail for use with astronomy mounts, and a 1/4" photo thread for use with regular photographic tripods.

This spotting scope is simply amazing i like to view with both eyes,having had a monk cyclop scope that also used a binoviewer i just can't be bothered with staining my eye viewing with one eye.I did not know what to expect with this scope the other option was the swarovski btx module that cost silly money i got this scope from flo ex dem for £500.00 i ordered on friday it arrived next day on saturday,Imy son and i set it up on a tripod when i looked through it my jaws just dropped to the ground AMAZING VIEW.My son who is not into optics every time i get a new piece of equipment he just snigger and laugh but when he looked thru the scope all i heard was WOW OMG DAD IT'S BRILLIANT SO BRIGHT.My monk cyclop bino-scope seems dim in comparison although it has 90mm objective i guess that's technology fot ya this is got to be the way forward this is technology at it's best,Even if i paid the full price i would not regret anyone who knock binoviewers saying they are dim should embrace this new technology try with an open mind they will be surprise.,the scope in made out of polycarbonate so it's very light when compared to large astro binoculars
