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

View nebulae and galaxies at maximum image brightness with your Newtonian telescope or your refractor. You do not 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 binoviewer 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 extreme wide-angle eyepieces are not recommended, but eyepieces with up to about 60° field of view are good.

Features

• 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.
• Especially high sharpness and better contrast 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 continuously adjustable from 58 mm to 74 mm.
• Diopter compensation at the right receptacle
• With 127x106x50 mm, the binoviwer is very compact.
• The weight is only 716 grams - the focuser is not unduly burdened.
