Next generation; retain only one optimal gear position brightness; reduce cumbersome manual adjustment; standard hex wrench to self-calibrate coaxial problem; the spot shape is a dot not a grainy elliptical point
High-end module design; the module adopts high-end spherical module, high sensitivity and easy adjustment; adopts 3-piece glued optical glass lens for stable spotting better focusing effect and less halo; make the spot shape is a dot instead of a grainy elliptical point
Adjustable collimator; external effects of the product during transportation and use may cause off-axis problems; you can calibrate the coaxial problem yourself by giving away the standard hexagonal wrench
The value must have 2x barlow lens doubles the magnification of any 1.25 inches eyepiece; double the capacity of an existing set eyepieces at the cost of a single eyepiece
SVBONY barlow lens provide a high power magnification allow you look more closely and more detailed at the moon's surface and other planet
وصف
SV121 red laser collimator perfectly align your reflector optics with our second-generation collimator, SV121 collimation eyepiece can be used for precisely collimating the newtonian and schmidt-cassegrain reflector telescopes for better image quality. High magnification for eyepieces to see more details of the moon; bands of Jupiter clearly; SVBONY 1.25" 2x barlow lens is a better choice.
