Omegon Flatfield 19mm 65° 1.25″ Eyepiece
The Omegon Flatfield 19mm eyepiece belongs to the Flatfield series and delivers a 65° apparent field of view. With a focal length of 19mm, it captures large areas of the sky in a single view - open star clusters, extended nebulae, or the full lunar landscape all fit comfortably in the frame. The SWA (Super Wide Angle) design keeps the image sharp and flat right to the edge of the field, with no noticeable curvature or softening towards the edges.
Multi-coated optics for a bright, clean image
The optics feature multi-layer anti-reflection coatings (Multi Coating) that reduce reflections and maximise light transmission. The result is a high-contrast, clear image - even when observing faint objects. The eyepiece fits any standard 1.25″ focuser and includes a filter thread, so no additional adapters are needed.
Comfortable to use - with or without glasses
The adjustable eyecup lets you observe in comfort whether you wear glasses or not. Simply set the eyecup height to suit your needs. The eye relief is 9mm, which is particularly useful for observers who prefer to keep their eye a natural distance from the lens.
Who is this eyepiece for?
The Omegon Flatfield 19mm eyepiece suits both beginners looking for their first quality wide-angle eyepiece and experienced observers building a deep-sky eyepiece set. The 19mm focal length sits at a practical midpoint between a wide overview and detailed magnification. It handles sweeping star fields just as well as targeted searches for Messier catalogue objects.

Why choose the Omegon Flatfield 19mm?
Wide-angle eyepieces with a truly flat field are not common at this price level. The Omegon Flatfield series delivers consistent sharpness across the entire field of view - something you will notice immediately when comparing it with standard Plössl designs. Whether you are observing the Andromeda Galaxy, sweeping through the Pleiades, or exploring the Moon, the 19mm focal length gives you the space to take it all in at once.
The included filter thread means you can attach a Moon filter or any other 1.25″ filter directly - no adapter required. This makes the eyepiece a practical, ready-to-use addition to any telescope setup.
