SVBONY SV121 Collimator Optical Alignment Eyepiece for Newtonian Telescope Alignment Maintains Only One Optimal Brightness Level Dotted Spot Includes

SV120 optical axis correction eyepiece upgrade. Only one optimal brightness level is maintained. Reduces troublesome manual adjustments. A standard hex wrench can solve self-calibration coaxial problems. The spot shape is a point rather than a granular ellipse. High-end module design; The module adopts high-end spherical module, which has high sensitivity and easy adjustment. Adopts a 3-piece cemented optical glass lens, achieving better focusing effect and less halo with a stable spot. Make the spot shape a point instead of a granular ellipse point. Adjustable collimator. External influences on the product during transportation and use can cause off-axis problems. You can calibrate coax problems yourself by gifting a standard hex wrench. Full metal structure, high-end atmosphere. CNC precision lathe processing has a front opening that allows light to exit. It can be used even at low temperatures, the spot size does not change even with sudden temperature changes, and it is resistant to extremely cold temperatures, with no effect on the effectiveness of use even in extremely cold temperatures of -30℃. 1.25" collimator with 2" adapter. Designed for precise collimation of nutorian and SCT reflector telescopes. The SV121 collimator employs maintaining only one optimal gear position brightness, reducing tedious manual adjustments. Further, the spot shape is not a granular elliptical point but a point. 1.This is the latest 1.25" collimator with 2" adapter. Easy to recognize and get accurate aiming direction. 2. This collimator is suitable for Newtonian and SCT reflecting telescopes 3. Equipped with 3 adjustable screws on the body, if the collimation is lost, you can adjust it manually. 4. Side windows allow easy collimation of the reflecting telescope optics. 5. Just insert it into the eyepiece holder, turn it on, and adjust the telescope screw to move the laser to the center of the primary mirror's center spot.
