Omegon Flatfield 16mm 60° 1.25″ Eyepiece
The Omegon Flatfield 16mm eyepiece offers a 60° apparent field of view - a combination that works equally well for sweeping views of large nebulae and star clusters, and for detailed planetary observation. Thanks to its SWA flat-field design, stars stay sharp all the way to the edge of the field of view, with none of the image curvature you often see in less refined eyepieces.
Clear, high-contrast views
The optics feature multi-layer coatings (Multi Coating) that reduce reflections and improve light transmission. The result is an image with good contrast and natural brightness - something that observers under dark skies will appreciate, where every photon counts.
Comfortable to use - with or without glasses
The adjustable eye cup lets you find a comfortable viewing position whether you wear glasses or not. The 9 mm eye relief is a standard value for the 1.25″ format and suits most observers well. A built-in filter thread makes it easy to attach a UHC, O-III, or Moon filter - no adapters needed.
Ready to fit your telescope
The Omegon Flatfield 16mm 1.25″ eyepiece connects to any standard 1.25″ focuser, so it is compatible with the vast majority of modern telescopes. Please note that this eyepiece is not filled with inert gas.

Who is this eyepiece for?
This eyepiece suits a wide range of observers:
- Beginners who want a reliable, versatile eyepiece for their first telescope
- Visual observers who enjoy wide-field views of nebulae, star clusters, and the Milky Way
- Planetary observers who need a moderate focal length for detailed views
- Observers who already use UHC or O-III filters and want the convenience of a built-in filter thread
- Glasses wearers who need an eyepiece with an adjustable eye cup
Why flat-field optics matter
Many standard eyepieces show stars that become blurry or distorted near the edges of the field. A flat-field design corrects this across the full 60° - so you see sharp, pinpoint stars from the centre right to the edge. This makes a real difference when observing open clusters or large nebulae, where the outer parts of the field matter just as much as the centre.
Filters - simple and direct
The built-in 1.25″ filter thread means you can screw on a Moon filter, a UHC narrowband filter, or an O-III filter in seconds. No extra adapters, no extra cost. This is a practical advantage that many cheaper eyepieces do not offer.
