SVBONY 216 2X Barlow Lens, 1.25” FMC Barlow Lens Telescope Accessory

The SV216 Barlow lens adopts a 4-piece telecentric design; which effectively prolongs the focal length of the primary mirror without introducing chromatic aberration and vignetting problems that bother users; offers excellent spherical aberration control; resulting in a flatter field of view than standard Barlow lens
The magnification of the SV216 Barlow lens is constant at 2 times; the 4-piece design of the Barlow lens and the optimized optical structure ensure that the magnification factor of the Barlow lens remains unchanged no matter where the Barlow lens is installed in the optical system
SV216 2x Barlow lens adopts 3 screws design and coaxial locking device; improving the concentricity of the optical axis of the system can significantly improve the quality of captured images
