Omegon UWA 6mm 66° 1.25″ Eyepiece
A wide 66° field of view sets this eyepiece apart from classic Erfle designs and gives you a noticeably larger slice of the sky. At the same time, it keeps image quality on a par with the popular Plossl SWA-58° series. The five-element optical design with multi-layer anti-reflection coatings delivers good colour contrast and solid correction - well suited to telescopes with a focal ratio down to f/6.
An eye relief of 14.8 mm means you can observe comfortably without pressing your eye precisely against the eyepiece. The body is fully metal, and all lenses are glass. A fold-down rubber eyecup adjusts for observers who wear glasses and those who do not. The standard 1.25″ filter thread accepts Moon filters, planetary filters and other accessories in seconds.
The wide field of view makes it much easier for entry-level observers to find and centre objects - whether that is a bright open cluster, a galaxy, or a nebula. The Omegon UWA 6mm eyepiece is a straightforward choice for anyone who wants reliable optics at a fair price, without unnecessary compromise.

Who is this eyepiece for?
Beginners
A wider field of view means it is easier to locate objects and keep them centred. If you are just starting out in astronomy, the Omegon UWA 6mm makes the learning process noticeably more enjoyable.
Visual observers on a budget
You get solid optics, a metal body and multi-coated lenses without paying a premium price. This eyepiece competes well above its price point.
Anyone upgrading stock eyepieces
Most telescopes come with basic eyepieces. The Omegon UWA 6mm is a direct, affordable upgrade that fits any standard 1.25″ focuser.
What can you observe?
At 6 mm focal length, this eyepiece provides higher magnification - useful for planets, the Moon, double stars and compact deep-sky objects. The wide field of view also helps when sweeping for star clusters and brighter galaxies. Adding a Moon filter via the built-in filter thread reduces glare instantly and improves surface detail on the lunar disc.
