An outstanding eyepiece. Extremely high contrast and a very comfortable view. A slightly older rarer version of the 25 mm zeiss jenaortho. Zeiss jena made the highest quality oculars.
It is optically excellent. Optics are perfect. Possibly slightly better than the newer 25 mm ortho's with plastic lens mounts. No scratches or coating flaws. Perfect optically.
Barrel has one or two set screw marks and black painted chromed brass part has a few scratches and some paint missing in two small spots.
These oculars are built to last a lifetime.
