Baader Glasspath Corrector - 1:2.6

Baader Glasspath Corrector - 1:2.6 - Maxbright and Mark V Binoviewers The Baader Glasspath Compensator serves multiple functions. In addition to correcting the color error caused by the long light-path through the binoviewer glass prisms (glasspath), the compensator also magnifies and extends the focal point of the telescope. This focal extending aspect is key to being able to use a binocular viewer in most telescopes. Due to the basic design of all binocular viewers, the distance that light must travel through the viewer is on the order of 4.5" or more (the Maxbright is the shortest viewer we know of, at 110mm). Many telescopes, especially Newtonians, do not have sufficient back-focus in order to reach focus with such an optically long accessory (ie, not enough focuser in-travel). By using a Baader compensator, the focal point of the telescope can be extended sufficiently to accommodate the length of the binoviewer. Baader Glasspath Corrector shown with option
