Binoviewer from TS Optics for telescopes for comfortable oberving with both eyes

Lead-managed by TS Optics, this high-quality binoviewer was developed especially for astronomical telescopes. The TS binoviewer is not a converted microscopic accessory, but a quality construction designed for practical use with telescopes.

The advantages of binocular vision:

Simply close one eye and compare the image. You will notice less details and tire faster. For this reason, landscape viewing usually is more relaxed with binoculars than with a spotting scope. Astronomical viewing with the TS binoviewer also has advantages:

• Viewing is tireless and more relaxed.
• Fine details, especially at moon and planets, are better perceived than with only one eye. This happens by superimposing the image information from both eyes in the brain.
• Seeing is better compensated, also an achievment of the brain.
• There is an impression of higher magnification and a more contrasty image.
• Nebulae, clusters and galaxies can also be observed well. Despite the light is distributed to two outlets, it looks only minimal dimmer, but the more vivid. A globular cluster or a bright nebula appears more structured and even offers a slight three-simensional effect.
  
  

The features of the TS binoviewer:

Viewer is not the same as viewer, as many amateur astronomers had to realize. With the TS binoviewer, there are no compromises.

• Eyepieces are clamped exactly on the optical axis b a compression ring. The brass ring encloses the eyepiece and centers it at the same time. Therefore tilting becomes impossible, double images are avoided.
• Similar to good binoculars, diopter differences are compensated by a micro focuser. You can put both eyepieces into the receptacles as far as they will go. Simpler binoviewers do not offer this, you have to pull out one eyepiece a bit. That is not very precise.
• With only 100 mm, the TS binoviewer has a short optical length. With a suitable glass path corrector, it can be completely compensated, making also possible the use with Newtonian telescopes. The corrector is simply screwed into the filter thread of the binoviewer´s telescope side 1.25" barrel.
• The prisms of the binoviewer are over-dimensioned and, of course, multi-coated. If you look into the viewer without eyepieces, you will see a circular opening without lateral shading. Annoying reflexes or multiple imagages are reliably avoided. You can concentrate exclusively on the object.
  The binoviewer is delivered with a solid matal case, all connections are covered by protective caps. Thus, the binoviewer will look like new even after many years.
  
  

Easy to use with almost all telescopes:

Generally, the TS binoviewer can be used with any telescope with 1.25" or 2" focuser.

• All telescopes with internal focusing (Schmidt-Cassegrain, Maksutov, etc.) allows for direct adaption of the binoviewer. The adjustment range is big enough.
• Refractor telescopes with 2" focusers also have a generous working distance from focuser to image plane. If you use a 1.25" diagonal, usually the TSGWK16 - 1,6x glass path corrector will be sufficient.
• Also Newtonian telescopes designed for astrophotography offer a suitable distance. The TSGWK16 will suffice.
• Newtonian telescopes with shorter distance or refractor telescopes with 2" star diagonal - wherever there is not too much space for focusing - need the stronger glass path corrector TSGWK26.
