Omegon Eyepiece Premium Flatfield 65° 25 mm

Omegon 65° Premium Flatfield Eyepiece, 25 mm focal length

Omegon Premium Flat Field Eyepieces - combining flattened image field with high contrast

Most eyepieces suffer from image distortion at the edge of the field of view. If you move the object observed into the outer part of the field of view it becomes distorted. Omegon premium flat field eyepieces counteract this effect. Who does not want a really true to life and undistorted image?

You can get really close to this ideal with flat field eyepieces. These flat field eyepieces have an ED lens element included which gives particularly good colour purity. Their optical construction also means that these eyepieces offer extremely high contrast and sharpness, way above the usual level.

The advantages of this eyepiece series in a nutshell:

Flat field optics, giving a flat, uncurved field of view

ED element for high contrast and image colour purity

Wide angle eyepieces with 60° to 65° field of view

Pleasant viewing experience

Multi-coating on all lens surfaces

At least 16 mm eye relief, suitable for spectacle wearers

Foldable eye cups (thread M34x0.75 below)

1.25" barrel, 25 mm long, with 1.25" filter thread (M28.5)

Wide field of view
With a 60° to 65° apparent field of view, these eyepieces belong to the wide angle eyepiece category. Classic ´tunnel vision´ eyepieces stay more and more in the drawer. Compared to the familiar Ploessl eyepieces, premium flat field eyepieces give a field of view which is around 20% wider.

The body of the eyepiece combines up to six lens elements, producing a really high quality eyepiece. All glass/air surfaces are multi-coated, preventing unwanted reflections and guaranteeing high brilliance and transparency. You can therefore expect extraordinarily good contrast when observing planets and DSOs through these eyepieces.

Between eye and eyepiece
These eyepiece series offer a particularly comfortable viewing experience. Even if the optical axis is not perfectly aligned, no vignetting occurs. This series features large eye lens diameters, allowing for comfortable viewing even at high magnifications. Even eyeglass wearers can use the eyepieces, as at least 16 mm eye relief allows the entire field of view to be seen while wearing glasses. The eyepieces can be used with most telescopes without problem. Even with Newtonian telescopes with a fast focal ratio of f/5, the edge of the field of view appears virtually edge-to-edge sharp.
