This eyepiece uses an internally mounted porro-prism which provides upright-correct images in reflectors. Excellent for terrestrial and lunar observing. No need to invert star maps! Will work with a refractor with no diagonal for a correct upright image.
50 degree apparent field of view, multi-coated optics, rubber eye-cup.
A wonderful observing experience that opens new vistas for your dob or equatorially mounted reflector.
