Baader Maxbright Telescope Binocular Viewer

Baader Maxbright Telescope Binocular Viewer

Back in 1996, we discovered for ourselves the benefits of observing with two eyes. The improvements are dramatic in the reduction of eye-strain, and the ability to comfortably concentrate on objects and discern faint contrasts. Using two eyes also serves to compensate for floaters and astigmatism, and in effect reduces the visual noise in images. These effects are equally dramatic for both planetary and deep sky viewing. Once you try viewing with two eyes, you will never want to go back to single-eye viewing again.

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. Their flagship, the Mark V Giant Binoviewer, has proven itself to be the finest no-compromise binoviewer ever produced for astronomy. Now, Baader has taken this know-how and combined it with low-cost Chinese manufacturing in order to vastly reduce the price for a true high-quality Baader astronomical binoviewer.

The Baader Maxbright-Binocular is not just a cosmetic variation of the same Chinese binoviewer everyone seems to be re-labeling these days. Baader Planetarium has worked extensively with their own independent partner in China to redesign critical elements of their viewer, as well as to train and bring the optical assembly and quality control processes up to their German standards. The result may cost a few dollars more than the clones, but we think the extra quality, performance, and features are worth the modest investment. In our own critical comparisons done at high magnifications on Mars, we found the performance of the Maxbright to be surprisingly comparable to our superb Mark V binoviewer.

In order to merge images at high magnifications, the optical centerlines of the two light paths must be kept accurately centered and squared, relative to the eyepieces and user's eyes. This requires very precise positional and angular alignment of all the optical and mechanical elements of a viewer. These sensitive alignments must be maintained over the life of the viewer, even after rough handling during shipment. To accomplish this critical factory collimation on each and every binoviewer, Baader has incorporated some key improvement.

Baader Maxbright Telescope Binocular Viewer Features

  • Proprietary Baader metal die-castings, featuring re-designed prism seats made to the same precision as the Mark V viewer.
  • Laterally adjustable eyepiece holders (with diopter adjustment and multiple clamp screws). Unlike the Chinese clone viewers, the Maxbright eyepiece holders are collimatable. This is an essential element to being able to fully collimate all viewers for work at high magnifications. They can even be removed and replaced in the future with high precision Baader Clicklock adapters (future availability).
  • Interocular separation range of 53mm - 74.5mm.
  • Full Multi-coatings on all air-to-glass surfaces. The excellent multi-coatings of the Maxbright-Binocular deliver a very bright and contrasty image.
  • 23mm diameter clear front aperture. Excellent illumination of all 1.25" eyepieces - even long focal length wide-field eyepieces. In our tests with a TeleVue 24mm Panoptic (68degree field) and the very fast Takahashi Sky 90 (f/5.6), there was a only a slight amount of vignetting (light cut-off) visible just inside the edge of the eyepiece field stop. When tested with a 21mm and 28mm Pentax XL, the field was brightly illuminated all the way to the very edge of the field stops.
  • T-2 System Modularity. The rotating knurled front T-thread ring enables the Maxbright-Binocular to fit all existing telescope makes with the shortest possible path length possible. The Maxbright comes standard with a removable 1.25" or 2" nosepiece to fit any telescope, but it may also be adapted to attach to a multitude of accessories and telescopes directly through the use of our Astro T-2 System. Through this system, the Maxbright may be directly close-coupled to just about any exotic thread; Vixen/Takahashi (M43x1, M36.4), Pentax (M43x0.75), Intes (M42x1), SCTs (2"x24tpi), AP (2.7"), Zeiss (M44), etc.

Questions & Answers

Ask a Question
  • CAN YOU USE A BARLOW WITH BINO VIEWERS?

    Yes you can, however doing so with Barlows meant for more "normal use" (eyepiece inserted directly) will likely result in magnification being different (greater) than expected. Baader does offer "Glasspath Correctors" for their binoviewer. These will work

  • I am interested in these viewers - -  Will this bino viewer work with a Meade Starfinder dobsonian : Focal Length: 1140 mm, F ratio: f/4.5. Or a 5" Maksutov Cas:  1540mm (f/12.1) focal length Or an 8" Meade Schmidt Cas:    f/10 optical system (focal lengt

    These binoviewers will work without additional accessories in a 1.25" diagonal with both the 5" Mak and the 8" SCT. They will not reach focus in the dobsonian without some sort of barlow corrector. The 1.7x corrector is the minimum needed to reach infinit

  • Can you use these with an erect image prism?

    Normally, no, unless you are using this on a scope specifically designed to have very long back focus like an SCT or some Takahashi and StellarVue refractors with a "binoviewing" mode. With a 1.25" erect imaging prism, this might work on a TSA-102, TOA-13

  • Thanks for your reply. I am thinking of buying an 8" sct, like a Meade ACF, and was curious about whether I could use the binoviewers and erect image prism on that type of scope.

    An 8" SCT should have enough back focus when using a 1.25" erect image prism and these binoviewers. I don't believe you will need the included 1.6x barlow, but you may on certain scopes.

  • Do you stock a 1.25 nose piece

    The Baader Maxbright Telescope Binocular Viewer comes standard with both a 1.25" and a 2" nosepiece.
