Features
:
SVBONY super-wide angle 1.25" zoom eyepiece.
The zoom eyepiece allows you to change magnification power without swapping out eyepieces.
5-Elements / 3-groups made of high index glass deliver sharp, high contrast vistas.
A simple twist of the zoom eyepiece housing changes the focal length from 30mm to 10mm, providing a variety of viewing magnification powers.
Exceptionally long 17mm-18.5mm eye relief range allows eyeglass wearers to enjoy the entire field of view without needing to remove their glasses.
Sleek black barrel with safety undercut to reduce the possibility of the eyepiece slipping out of the focuser or diagonal.
Blackened lens edges, anti-reflection threads for maximum contrast.
