Key Features
Finally we can introduce the MaxBright II Binoviewer. It closes the gap between cheaper entry-level binoviewers and Baader's high-end Mark V Giant Bino.
- 27mm prisms with 26/25.5mm clear aperture and for all 1.25" eyepieces (up to focal lengths of 35mm)
- Ergonomically designed ClickLock eyepiece clamps with diopter adjustment
- Baader Astro T-2 System connector thread (M42x0.75) and Zeiss micro-bayonet for the shortest possible connection to (almost) all existing telescope systems
- Scope of delivery: Baader MaxBright II Binoviewer with adapters to T-2 and Zeiss micro-bayonet in a padded carrying case
- Optical tube length: 110 mm (+/- 1 mm tolerance)
- Weight: 595g (200g lighter than Mark V) - binoviewer body only
- Includes:
- Baader Nose piece and Camera Adapter 2" / T-2 (T-2 Part #16) (# 2408150)
- Glasspath Corrector 1:1.70 for Baader-Binoviewer with T-2 thread (MaxBright II and MaxBright) (# 2456316)

Description
"Supercharged" by design
The MaxBright II Binoviewer incorporates the knowledge aquired during thirty years of building astronomical binoviewers. It is superior to cheaper models in many details.
Comparison of the free aperture of the new MaxBright II Binoviewer and the discontinued MaxBright Binoviewer
- The housing of the 27mm large prisms is made with Baader's own die casting moulds, using Carl Zeiss production drawings. The non-slip leather finish provides extra grip when holding the binoviewer with heavy eyepieces in your hand.
- On the eyepiece side, the newly designed, self-centering Clicklock eyepiece clamps with diopter adjustment are immediately noticeable. Thanks to the ergonomic design, you can blindly distinguish between clamping and diopter compensation even in the dark. The inner parts are made of stainless steel for maximum stability. The high-quality eyepiece clamps are only the last part of the precisely collimated optical system, which is designed for highest magnifications. This is the only way to achieve the almost three-dimensional image and relaxed observation expected from a binoviewer.
- All optical surfaces of the Maxbright II feature a 7-layer multi-coating. The prism chairs (mounts) of the prisms are constructed like those of the Mark V Großfeld (Giant)-Binocular (#2456410). The clear aperture is 26 mm on the telescope side and 25.5mm on the eyepiece side – even Baader's 35 mm Eudiascopic eyepieces are illuminated without vignetting. In comparison to models with smaller prisms you can see a much larger part of the sky at the same magnification – similar to Baader's Mark V Großfeld (Giant)-Binocular (#2456410) .
- On the telescope side, either a T-2 cap nut or a dovetail ring with original Zeiss micro bayonet are available – both connection options are included in the scope of delivery and allow a very compact adaptation to all common threads as well as Baader's T-2 prisms and mirrors. Compared to fixed nosepieces, this effectively saves a lot of backfocus. The MaxBright II is compatible with all Baader Glasspath correctors. According to optical calculations by Carl Zeiss, these correction lens systems shift the focus outwards so that you can still reach focus despite the approximately 11 cm back focus (the required inward travel of the focuser) of the binoviewer. They also compensate for the color error that would otherwise be introduced through the prisms when using telescopes between f/4 and f/7. Glasspath correctors are not simple Barlow lenses, even if they resemble them. For this reason, in Germany the name Glaswegkorrektor® is a protected trademark by Baader Planetarium.
Listed below are some common applications and accessories you can add to the binoviewer:
- In combination with a lens telescope or a Schmidt-Cassegrain, Baader recommends the Baader T-2 Stardiagonal (Zeiss) Prism with BBHS coating (T-2 part #01B or 2456095) or the Baader FlipMirror II Star Diagonal (#2458055) to achieve a compact telescope adaptation. In addition, you can then choose a matching Glasspath corrector. To select the right Glasspath corrector, you need to know the backfocus of your telescope. You can read how to do this in the Manual of the Maxbright II Binoviewer.
- For Newtonians, Baader recommends either the large 2" Glasspath corrector 1.7x for Newtonians (#2456301) or the Glasspath corrector 1:2.6x for Baader-Binoviewer with Zeiss ring dovetail (MaxBright II and Mark V) (#2456317).
- For SCs or lens telescopes, Baader recommends either the 2" Glasspath corrector 1.8x for Refractors and SCTs (#2456305) or the two T-2 Glasspath correctors - Glasspathcorrector 1:1.25 for Baader-Binoviewer with T-2 thread (MaxBright II and MaxBright) (#2456314) and Glasspathcorrector 1:1.70 for Baader-Binoviewer with T-2 thread (MaxBright II and MaxBright) (#2456316). The 1.25x Glasspathcorrector is used on lens telescopes mainly for removing the color aberrations which would otherwise be introduced by the long light path through the prisms of the binoviewer.
- You don't necessarily need a Glasspath corrector for f/10 Schmidt-Cassegrains. Especially for lower magnifications and thus larger fields of view, the Alan Gee Telecompressor Mark II (T-2 part #20) (#2454400) is more interesting: It shortens the focal ratio to approx. f/5.9, which gives you a brighter image and a larger field of view. So a C8 almost becomes a rich-field telescope for comfortable observations with both eyes open!
In addition to this basic viewer, the Baader MaxBright Binoviewer is also available in several packages for different applications at a discounted price.
