Baader Planetarium 1.25" FR-4 Focusing Ring Collar


Baader Planetarium 1.25" FR-4 Focusing Ring Collar

New, lower profile.  Baader Planetarium's Ring Collar slips onto your 1,25" eyepiece barrel, and enables you to adjust and lock a reference stop for repeatable eyepiece focus.  This allows you to set an eyepiece to be precisely parfocal with another eyepiece or piece of equipment (i.e. setting an eyepiece parfocal with a CCD camera for visual framing and focus).  Multiple collars can also be useful in pre-setting Bino-Viewer eyepieces for repeatable focus (to compensate for eye-to-eye focus differences).  The focusing collar is 0.23" (6mm) thick, and incorporates two nickel plated brass lock screws, which are tip radiussed to minimise eyepiece barrel damage.
