RK Eyepiece 10mm & 25mm - 1.25" - Three Element - MgF2 Coating
RK eyepieces are an improved variant of the classic Kellner design. The field sharpness is improved and the viewing comfort is better than in Plossl eyepieces of the same focal length. RK eyepieces are the ideal choice for astronomers, looking for a low cost but good quality eyepiece. The somewhat longer eye relief makes them well suited for beginners. The RK eyepieces have rubber eyeguard as protection against stray light. The eyeguard can be folded down for eyeglass wearers.

The RK 10mm
The eyepiece has a long eye relief. Even beginners will have no difficulty viewing the entire field of view. The RK 10mm is a low cost good quality eyepiece for many applications. The field stop is positioned in front of the lenses. This makes the eyepiece a good choice building yourself a crosshair eyepiece..

The RK 25mm
The eyepiece has a long eye relief. Even beginners will have no difficulty viewing the entire field of view. This is a low cost good quality universal eyepiece and is warmly recommended for binoviewers. It also serves as a nice general utility eyepiece with a good transmission.
