Baader Binoviewer System and Accessories

Baader MaxBright® II Binoviewer with adapters to T-2 and Zeiss micro-bayonet in a padded carrying case

The MaxBright® II Binoviewer incorporates the knowledge acquired during thirty years of building astronomical binoviewers. It is superior to cheaper models in many details.

With over 20 years of binoviewer experience, Baader Planetarium is the world's expert in in the design and production of high-end Astronomical Binocular Viewers.

Baader has designed the Maxbright II Binoviewers with over thirty years of building some of the best astronomical binoviewers the world has ever known.

Not just another me-too optical multiplier/extender

For Schmidt-Cassegrain-telescopes with 2" eyepiece clamp or for direct connection to SC-thread through Baader T Adapter (BTA) for SC and MAK Telescopes (T-2 part #21) (#2408160) or Baader SC / HD Ultra Short T-Adaptor, 7mm optical length (#2958500B)

One of the main features of Baader T2 diagonals is the large free aperture they offer

Glasspathcorrector Factor 2,6. Optical path length: -120 mm
Insert diameter: ∅ 38 mm

A glasspathcorrector fulfills two purposes: It removes the colour aberrations which are caused by the prisms of the binoviewer at fast telescopes, and it moves the focus point outwards so that you can reach focus even at telescopes with little backfocus.

Glasspathcorrector Factor 1,7. Optical path length: -65 mm

A glasspathcorrector fulfills two purposes: It removes the colour aberrations which are caused by the prisms of the binoviewer at fast telescopes, and it move the focus point outwards so that you can reach focus even at telescopes with little backfocus.

the Baader Glasspath Corrector 1:1.25 magnifies and extends the focal length of the telescope while correcting color error caused by the long light-path through the binoviewer glass prisms.

-2 (M42x0.75) Locking ring with lever for direct attachment of the MaxBright® II onto all Baader T-2 star diagonals, prisms or mirrors (e.g. to directly couple the body of the Maxbright II with the Baader Prism Diagonal T-2/90° 32mm (#2456005)

- To adapt long focal length eyepieces (30-42mm) onto Maxbright Bino-Viewer
- 2 pieces required for Baader Maxbright Bino-Viewer

Maxbright II Bino rotation lock/auxillary-ring – for the shortest possible adaptation of the Maxbright® II Bino directly onto all Baader T-2 star diagonals, be it prisms or mirrors – without any part in between that would cause an increase in optical leng
