Legendary orthoscopic design for the best possible high magnification planetary observations or projection photography. Recommended for telescopes with focal ration above f/5.

Specifications
Focal length: 4.8mm
Apparent field of view: 48 degrees
Eye relief: 4.2mm
Fully multi coated optics
Full metal body
Standard 28.5mm filter thread

Blackened internal surfaces of eyepiece barrel to eliminate internal light scattering.

Test results:
We have tested one of the 4.8mm orthoscopic eyepieces and compared with a simple 4mm Plossle of well known brand. Whilst the Plossl showed sharp image only in the center of the image, the ortho was beautifully crisp to the edge of the field of view all around.
This is one of the best purchases on the market and is well worth of the money.
