HoTech - 1.25" SCA Laser Collimator (Dot) - SCA-1.25D

Description Built-in Self Centering Adapter No more loose fitting laser collimators! Our patented Self-Centering Adapter cleverly eliminates the slop problem by using expanding rubber rings. As the rings expand, each ring fills the focuser slop and center positions the laser collimator in the drawtube. The SCA mechanism accommodates most brands of focusers allowing repeatable installation for an accurate collimation. High Accuracy Laser Alignment We position the laser precisely in the exact optical path and align the pointing of the laser beam parallel to the optical axis. It is critical to keep the laser beam centered along the optical path for an accurate collimation, otherwise collimating with an off-axis laser beam will introduce astigmatism into your telescope. Includes 45¼ Faceplate Viewer w/ Laser Engraved Targeting Grid The faceplate viewer helps to display the returning laser with a clear visual reference during collimation adjustment. The faceplate allows you to align your p
