Omegon Ortho 24mm Eyepiece (1.25 inch)

Omegon Ortho 24 mm eyepiece (1.25 inch): orthoscopic sharpness for planets

The Omegon Ortho 24 mm deliberately opts for the opposite of the wide-angle trend: a classic orthoscopic design with only four lenses, fully focused on maximum sharpness and contrast.

Less glass means less light loss and fewer reflections. For planets, the moon, and double stars, orthoscopic eyepieces therefore often reveal just that little bit more detail than more complex designs in the same price range.

Why orthoscopic surgery works

Four lenses in two groups, each surface multi-layered coated: every transition that can scatter light is one too many, so there are as few as possible. The image is calm, rich in contrast and colour purity, exactly what planet observers are looking for.

The downside is a deliberately compact field of view. Those who want a panorama choose a wide-angle series; those who want detail are well catered for here.

Practical to use

The rubber eye shell keeps stray light out, and the 1.25-inch aperture has filter thread for moon and color filters.

What do you see with 24 mm?

On a telescope with a 1200 mm focal length, 24 mm gives a magnification of 50x. The entire moon disc in one richly contrasting image, and a convenient focal point of focus for clear objects.

Even for entry-level orthopaedic examinations, the 24 mm is the most accessible choice.

Featured accessories

Combine two or three Ortho focal points for a complete planetary set, or use an Omegon Barlow lens to double the range. A moon filter screws directly into the filter thread.
