Introducing the new EAF, the latest innovation from the engineers at ZWO. This electronic focuser enables precise, dynamic focus control for planetary and deep-sky imaging. New version 5 volts

• Containing: T-2/32 Diagonal with focusing 1¼" eyepiece clamp (#2458125) and 1¼" nose piece (#2458105)
• Connection objective side: T-2 internal thread 1¼ "barrel
• Connection eyepiece: T-2 external thread and focusable 1¼ "eyepiece
• Excellent for Baader Maxbright binoviewer

• Much larger prism as in the so-called "Erecting prism"
• Many Erect image prisms have only 19 mm free passage opening and therefore are not suitable for terrestrial observations at low magnifications, because the field of the eyepiece is shaded by the too small prism.

• High-quality lense system with apochromatic features, for magnifications from 2x
• Modular design for visual and photographic (VIP) use
• suitable for 1¼" and 2" focusers

• Baader Q-Barlow lense 2.25x, 1¼" barrel
• dual factor lens assy (1.3x/ 2.25x)
• Modern High-Transmission Multi-Coating all air-glass surfaces delivers a remarkably brilliant image with extremely low internal reflections
• Extends the possible focal lengths of the Q-Turret eyepiece set

Finally Baader introduces the MaxBright® II Binoviewer. It closes the gap between cheaper entry-level binoviewers and our high-end Mark V Giant Bino.

• 27mm prisms with 26 / 25,5mm clear aperture, 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 (M 42 x 0.75) and Zeiss micro-bayonet for the shortest possible connection to (almost) all existing telescope systems
