Product Details
It's large clear aperture avoids vignetting, even with the Baader Mark V Giant Binoviewer. The finest 7 layer multi-coatings available provide extremely high transmission optimized for visual use. Carefully designed and executed internal baffling eliminates all off-axis stray light - pointing the corrector to the light reveals a pitch black interior free of reflections from all internal surfaces (also, threaded for 2" filters). This is especially important in truss tube Newtonians, where off-axis light may enter the corrector from the side. The result is an almost transparent optical system that won't reduce image quality in any way (it actually improves the off-axis performance). Each Newtonian compensator corrector comes ready to attach to the Baader Maxbright-Binocular viewer. Simply screw on the included T2-07 Quick Change Ring to the Maxbright, and the Newtonian Compensator quickly attaches via it's integral quick change dovetail. The compensator also attaches directly to the integral dovetail of the 29mm aperture Baader Mark V Giant Binoviewer. Please Note: The Baader 2" compensator has been designed first, and foremost, for high image quality. While the Newtonian Compensator greatly reduces the needed back-focus, in order to achieve such high image quality, some back-focus is still required. When used with the Baader Mark V binocular viewer, approximately 32-38mm of telescope back-focus (focuser in-travel) is needed. The Baader Maxbright-Binocular Viewer requires approximately 30-36mm of back-focus. This value is approximate, and depends on the specific eyepiece used and any focus correction that is required by the observer's eyesight. This distance is Not adjustable (unlike some bino multiplier/extenders). Changing the optical spacing (and amplification factor) in order to vary back-focus compromises the optical performance and results in a reduction of image quality.
