![]() This makes collimation faster than the traditional three- or six-screw collimation methods used with conventional finder brackets. The bracket has two hand-adjust collimation screws that work in conjunction with a third spring-loaded post in the bracket. The bracket is held in place in the mounting shoe by a single large hand-tighten knob that maintains the finder’s collimation, even if the finder is removed between observing sessions. The 8 x 50mm finderscope mounts in a quick release bracket that slips into a pre-installed metal mounting shoe nearer the focuser. This little telescope will show many objects in direct vision for easy location. Powerful 8x50 finderscope, multicoated objective lens. Physical Copies of the manual will not be given.
