These highly rated D21 eyepieces are matched to 1/100th focal length. Typically being 21.6mm, they have a 65 degree AFOV and of course are fully multi-coated.

They exhibit NO pin cushion distortion and produce amazing contrast, whether used for nighttime observations of planets, lunar and DeepSky or daytime views in white light and H-Alpha (Sun). Please be sure to ALWAYS use an appropriate protection filter when viewing the Sun!!!
