The Alpine Astronomical Baader MaxBright II Binoviewer allows you to enjoy views of the night sky without the strain and aggravation of having to hold an eye closed while looking through your eyepiece. Using two eyes to view reduces eyestrain while letting you comfortably concentrate on objects and discern faint contrasts. It also serves to compensate for floaters and astigmatism and lowers the visual noise in images. The 26mm telescope-side aperture fully illuminates eyepiece focal lengths up to 35mm, and the precise collimation of the seven-layer anti-reflection fully multi-coated prisms provides perfectly aligned light paths through your eyepieces and into your eyes.

For visual observation, the viewer is outfitted with dual 1.25" ClickLock eyepiece holders. This unique eyepiece mounting system is superior to conventional compression ring and set screw holders, using three long roller bearings to hold the eyepiece firmly centered in place without marking or marring it, while eliminating wobble and off-axis tilt. A simple twist locks and unlocks the clamping system for fast eyepiece changes even while wearing gloves. To mount the binoviewer into your optical tube, there are standard M42 T-threads that make it compatible with the entire Baader Astro T-2 modular accessory system, including 1.25" and 2" nosepieces, SCT visual back adapters, spacers, and more. This version of the MaxBright II comes with a Zeiss micro-bayonet dovetail mount adapter ring for those optical tubes and accessories that are outfitted with that connection. To protect your binoviewer, a hard ABS case with a custom cut foam lining is included.

The MaxBright II is compatible with Baader Glass Path Correctors that allow you to achieve the proper backfocus while also compensating for chromatic aberration (color fringing) and spherical aberration common in all binoviewers.
