This argument prevents many people from trying out for themselves what a revolutionary effect binocular vision has. But what is forgotten is that 50% of the light reaches \u003cstrong\u003eeach \u003c\/strong\u003eeye and that the energy from both eyes is “reunited in the brain” (more precisely, in the back of the head).\u003c\/p\u003e\n\u003cp\u003eWhat you then see is by no means 50% darker than it is claimed.

It has a number of features that makes the MK II superior to cheaper models.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe housing with large 27mm prisms is made with Baader’s own custom 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.\u003c\/li\u003e\n\u003cli\u003eAll 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, and means even Baader’s 35mm 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 our Mark V Großfeld (Giant)-Binocular (#2456410) .\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg alt=\"Comparison of the free aperture of the new MaxBright® II Binoviewer and the discontinued MaxBright® Binoviewer\" data-src=\"\/\/cdn.shopify.com\/s\/files\/1\/0014\/5909\/3576\/files\/maxbright_ii_vs_i_grande.gif?v=1565792957\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0014\/5909\/3576\/files\/maxbright_ii_vs_i_grande.gif?v=1565792957\" class=\"ls-is-cached lazyloaded\" decoding=\"async\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOn the eyepiece side, the newly designed, self-centring 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.\u003c\/li\u003e\n\u003cli\u003eOn 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 our T-2 prisms and mirrors. Compared to fixed nosepieces, this effectively saves a lot of backfocus. The MaxBright® II is compatible with all Baader Glasspathcorrectors. 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 colour error that would otherwise be introduced through the prisms when using telescopes between f\/4 and f\/7. Glasspathcorrectors are not simple Barlow lenses, even if they resemble them.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eAccessories\u003c\/h6\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eDiagonals\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIn combination with a lens telescope or a Schmidt-Cassegrain we recommend the Baader T-2 Stardiagonal (Zeiss) Prism with BBHS ® coating (T-2 part #01B) (#2456095) or the Baader FlipMirror II Star Diagonal (#2458055) , to achieve a compact telescope adaptation.
