Omegon UWA 15mm 66° 1.25″ eyepiece
If you are looking for an eyepiece that offers comfortable, spacious views without compromise, the Omegon UWA series is exactly what you need. The model with a 15mm focal length and a 66° apparent field of view is a versatile performer - suitable for sweeping nebulae as well as planetary and lunar detail. This eyepiece appeals to beginners and experienced astronomers who value quality optics at a reasonable price.
Fully multi-coated optics for bright, high-contrast images
The UWA (Ultra Wide Angle) series features fully multi-coated optics throughout the entire optical system. This ensures high light transmission, effective suppression of unwanted reflections, and excellent image contrast. With a 15mm focal length and a 66° field of view, you get a pleasantly spacious image that gives the observer a true "immersed" feeling - the classic wide-angle eyepiece experience.
Comfortable viewing with or without glasses
The 13mm eye relief is sufficient for comfortable viewing both with and without glasses, although users with strong corrections may prefer models from the series with a longer eye relief. A fold-down eyecup lets you quickly adapt the eyepiece to your needs - fold it down when observing with glasses, or extend it to center your eye precisely when observing without.
Standard 1.25″ barrel with filter thread
The eyepiece uses a standard 1.25″ barrel, making it compatible with the vast majority of telescopes and focusers on the market. At the base of the barrel you will find a 1.25″ filter thread, so you can easily attach a Moon filter, UHC, or OIII filter for observing emission nebulae. The eyepiece body is robust and sits well in the hand, with a solid transition between the rubber grip and the metal components.
Ideal magnification range for a wide variety of objects
The Omegon UWA 15mm eyepiece works excellently as a general-purpose eyepiece for medium magnifications. Here are some typical examples:
| Telescope focal length |
Magnification with UWA 15mm |
Best suited for |
| 600-900mm (refractor) |
40-60x |
Open clusters, larger nebulae, Moon |
| 1200mm (Newtonian) |
approx. 80x |
Lunar detail, globular clusters, galaxies |
At these magnifications, open clusters, larger nebulae such as the Orion Nebula or the Lagoon Nebula, and lunar surface detail all look spectacular. The filter thread makes it a practical foundation for visual deep-sky observing with an OIII or UHC filter.
