BINOCULAR VIEWER
INSTRUCTION MANUAL
Congratulations on your purchase of the Baader MaxBright Binocular Viewer. This is a very sophisticated optical
accessory that, if used in the right way, will offer you amazing views for all your life. To obtain the maximum
performance from the viewer, we suggest you spend a little time reading this instruction manual before starting to use it.

Insert the Binocular Viewer in the telescope's eyepiece holder and tighten the set screw(s) to hold the binoviewer in
place.
Optical distance, Back-Focus and Glasspath
compensator
To pass through the binoviewer and reach the eyepieces, the cone of
light coming from the telescope covers a path of about 100-110 mm.
Therefore the telescope must have a back focus (the travel of the light
outside the focuser) of at least 110mm in order to be able to reach
focus when used with the binocular viewer. So, several factors must
be considered:
1)
The majority of the Newtonians present a very short back focus,
usually no more than 30-60 mm; as a result, a typical Newton
telescope doesn't allow the use of a binoviewer without the use of
a back focus compensator.
