About This Product

The SV191 is a 1.25 inch eyepiece with variable magnification over a focal length range of 7.2mm-21.6mm. The lens is made of 7 elements/4 sets of multi-coated high refractive index glass, allowing for sharp, high-contrast observations. The lens edges are matte black to prevent stray light. The long eye relief of 18mm~20mm (17.5mm) allows you to wear glasses without compromising the view through the eyepiece.

■Zoom eyepiece

Simply twist the zoom eyepiece housing to change the focal length and obtain different magnifications.

■1.25 inch eyepiece

Ultra-wide 1.25" zoom eyepiece allows you to change magnification without changing eyepieces.

■Lens structure: 7 lenses/4 pairs

The lens is made of 7 elements/4 sets of multi-coated high refractive index glass, allowing for sharp, high-contrast observations. The long eye relief of 18mm~20mm (17.5mm) ensures a clear field of view through the eyepieces even when wearing glasses.

■Materials

The lens edges are blackened to prevent stray light and produce good images with high contrast. It has a safety undercut to reduce the possibility of the eyepiece slipping off the focuser or zenith mirror.
