The MaxBright® II binocular approach closes the gap between the affordable entry-level models and the high-end Großfeldbino Mark V from Baader.
- 27mm prisms with 26 / 25.5mm free passage, illuminates all 1.25 "eyepieces - up to 35mm focal length
- Ergonomic ClickLock® eyepiece clamps with diopter compensation
- T2 connection thread (M 42 x 0.75) and ZEISS micro bayonet enable the shortest connection to (almost) all existing telescope systems.
A padded case is also included.
The MaxBright® II binocular approach stands out in numerous details from cheaper models:
- The housing, which houses the 27mm prisms , is made from the large field binocular according to original Carl ZEISS construction drawings. The non-slip leather covering provides additional grip when you hold the binocular 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 stainless steel eyepiece holders, they offer maximum stability. The high-quality clamps are the last part of the precisely collimated optical system, which is designed for the highest magnifications.
- In the Maxbright® II all optical surfaces are 7-layer multilayer anti-reflective. The prism chairs (brackets) now correspond to the construction in the Mark V large field binocular. The free opening is 26 mm on the telescope side and 25.5 mm on the eyepiece side - this even illuminates our 35 mm eudioscopic eyepieces without vignetting.
- On the telescope side, either a T2 union nut or a ring swallow with the original ZEISS microbayonet are available - both connection options are included in the scope of delivery and enable short-term adaptation to all common threads. Compared to permanently installed receptacles, this effectively saves a lot of overall length.
For use on a refractor or Schmidt-Cassegrain , we recommend or in order to achieve the shortest possible optical length.
The MaxBright® II is compatible with all Baader glass path correctors® . These correction lens systems shift the focus to the outside, so that despite the approximately 11 cm back focus of the binocular, you can still get into focus. They also compensate for the color error that would otherwise be introduced by the prisms on telescopes between f / 4 and f / 7. Glass path correctors® are not simple Barlow lenses, even if they resemble them. For this reason, the name Glaswegkorrektor® is also protected under trademark law.
To select the Glaswegkorrektor® you need to know the back focus of your telescope; Instructions for determining the back focus can be found in the operating instructions for the Maxbright® II binocular.
- For Newtonian mirror telescopes we recommend either the large one or.
- For Schmidt-Cassegrains or refractors we recommend the or or. The 1.25x Glaswegkorrektor® on refractors mainly serves to eliminate a color error that would otherwise be visible through the long glass path of the binocular prisms.
- A Glaswegkorrektor® is not absolutely necessary for the Schmidt-Cassegrain with f / 10 . This is a more interesting option, especially for lower magnifications and larger fields of view: it shortens the aperture ratio to around f / 5.9, which enables a brighter image and a larger image field. This is how a C8 almost becomes a widefield telescope - with comfortable two-eye view!
More about binocular approaches: With one-eyed vision, you use your brain only to a fraction of its "computing capacity". Indeed, there is an "emergency circuit" in the brain so that image information obtained with one eye can be distributed to both hemispheres of the brain, however, the brain has no way of correctly interpreting the "image errors" and especially the "nerve noise", which inevitably occurs during energy transport occurs - just like a CCD image!
Just as you, as the owner of a CCD camera or webcam, overlay several pictures on the monitor, ie "process" pictures, the brain can also overlay the different information from both eyes when viewing with both eyes and in this way - in milliseconds every time - all defects calculate out that do not represent an effective picture element.
So it's no wonder if you have to take a few minutes to take a break, which your brain demands, because it is simply overloaded by the extremely concentrated look. The problem does not exist with binocular vision! You look as long as you want and stay relaxed. Even with severely limited eyesight in one eye, the lower tension results in an enormous gain in observation quality.
One often hears the criticism that the use of a binocular approach would split the light into two visual channels and that only 50% of the light intensity arrives in each eye. With this argument, many people are prevented from trying out for themselves what a revolutionary effect binocular vision has. But what is forgotten is that 50% light arrives in each eye and that ultimately the same energy "in the brain" (- more precisely - in the back of the head) is reunited.
So what you see is by no means 50% darker than is claimed. The real gain is only visible to someone who has tried it out for themselves and has become familiar with this type of vision for a few minutes. Ultimately, the picture does not look darker, but more detailed, effortless and beautiful.
