TS-Optics Binoviewer 1.0 magnification zero optical path and erect image

TS-Optics Binocular Device without change in focal length and complete correction of the optical path.

View nebulas and galaxies at maximum image brightness with your Newtonian telescope or your refractor. You don´t need an additional lens or corrector for compensating the length of this binoviewer and the magnification stays the same. That is made possible through a new mirror prism concept and corrector system.

The parfocal 1.25" binoviewer allows deep-sky observation with both eyes even at low magnifiation, so you can fully use the speed of your telescope.

The PFBINO is optimized for 1.25" eyepieces up to approximately 22 mm field stop diameter. 100% clear aperture is reached with a field stop of 17.3 mm. For this reason we do not recommend extreme wide-angle eyepieces, but our NED eyepiece series which can be used without limits.

Features of the TS PFBINO at a glance:

Complete optical path compensation, the position of the focuser stays roughly the same as without the binoviewer. You can use the binoviewer with all telescopes with 1.25" receptacle.

The magnification does not change, this is achieved through a combination of mirrors, prisms and corrector lenses.

The workmanship is of particularly high quality and classy - made in Taiwan.

Especially high sharpness and better conrast than with simpler binoviewers.

Ideal for fast APO refractors with little backfocus and for all Newtonian telescopes.

The binoviewer can be combined with all current Barlow lenses.

Telescope side connection is 1.25" - using 1.25" filters is possible.

Eyepiece side connection is also 1.25", eyepieces are locked with compression rings - thus free from tilting.

The interpupillary distance is continously adjustable from 58 mm to 74 mm.

With 127x106x50 mm, the binoviwer is very compact.

The weight is only 716 grams - the focuser is not unduly burdened.

Innovative Binocular with Upright Image and Without Extending Optical Path

Thanks to the integrated erecting system with seven lenses in five groups, binocular viewing with an erect image and without changing the magnification is possible, allowing use with almost all telescopes without the use of extenders, etc. Instead of an ordinary beam splitter prism, a precision polished knife-edge mirror is used for the optical beam splitter system. As a result, the difference in hue between left and right and the difference in brightness are small, and there is also no occurrence of various aberrations due to the use of the prism and no reduction in contrast, so a very clear binocular image can be obtained. In addition to observing the moon and planets at high magnification, it is possible to use the special 0.66x reducer, so you can enjoy observing large-scale objects at low magnification.
A bino for Newtonian telescopes usually have a short working distance, which often makes it impossible to use a bino. The PFBino, on the other hand, can be used on almost all Newtonian telescopes.
If you want a 45 or 90 degree angled view and value an upright and laterally correct image (e.g. for earth observation), you can achieve this with the special prisms linked under "Recommended Accessories".
