2 Sets of 4-piece Optical Structures

Plossl eyepieces correct color and spherical aberrations very well and provide a flat field, which means the objects that you look at are not fringed in color and distortions will not appear on the edge of the field of view.

Fully Multi-coated

Fully multi-coated optics, it ensures that each glass surface has multiple layers of coating to for a better image quality.

Apparent Field of View: 50°

This 50°Field of View is wide enough to be generally comfortable viewed and makes this eyepiece ideal for a variety of observational purposes including deep-sky and planetary viewing. 

Matt Blackened Lens Edge

The design improves the efficiency since less light is lost due to reflection and improves the contrast of the image by elimination of stray light. All-metal mirror structure, fine texture, fine workmanship.

Safety Undercut

Safety undercut milled into the nosepiece to prevent the eyepiece from falling out of the focuser.

With or Without Glasses

Plossl eyepieces with 15mm and longer focal lengths are good choices for spectacle wearers but for shorter focal lengths, the SV190 series have greater eye-relief and are better suited.
