Binocular Viewers

The Altair wide-field binoviewer allows vignetting-free observations with almost all 1.25" eyepieces through oversized prisms.

• Clear aperture 28 mm / prism diameter 30 mm
• 1.25 connection on the telescope
• Prism surface Lambda/8
• Self-centering eyepiece connection for perfect fit of the eyepieces, also with safety groove
• Built-in micro focuser for diopter compensation on each side
• Short design with only 118.5 mm optical path - can be used with many refractors without compensating the optical path
• Robust transport and storage case included in the scope of delivery

The binoviewer from TS was especially designed for the use with telescopes and offers comfortable viewing with both eyes.

• Perfect on-axis clamping of the eyepieces by compression rings - no tilting possible, thus no double images
• Diopter fine adjustment and micro focusing via knurled wheel - not necessary for pulling the eyepieces back
• Generously dimensioned prisms with 23 mm clear aperture without lateral shadings for a good illumination
• No reflexes or multiple images through full multi-coating and neat internal blackening
• Very well adjusted prisms - no double images!
• Only 100 mm optical length - together with the matching glass path corrector, using the binoviewer with Newtonians is possible
• Only 525 grams - well suitable for more simple focusers, too.
