Omegon Panorama II 21mm 100° 2″ eyepiece
If you are looking for an eyepiece that will truly immerse you in the night sky, the Omegon Panorama II 21mm is exactly what you need. A wide-angle eyepiece with a 100° apparent field of view offers one of the most expansive views any astronomer could wish for - nebulae, star clusters and the sweeping structures of galaxies unfold before you in all their glory, with no sense of peering through a keyhole. The Panorama II series from Omegon is designed for demanding astronomers who refuse to compromise between observing comfort and optical quality.
Optical design
At the heart of the eyepiece is a 7-element optical system with multi-layer anti-reflection coatings on all optical surfaces. Light transmission is maximised as a result, and image contrast remains high even when observing faint deep-sky objects. What truly stands out, however, is the sharpness of the image right to the very edges of the field of view - a quality that is far from guaranteed in wide-angle eyepieces with such a large apparent field. The Omegon Panorama II 21mm is fully compatible with fast telescopes at f/4, where most cheaper wide-angle eyepieces fall short. This makes it a versatile choice for owners of Dobsonians, Newtonians and short-focal-length refractors alike.
Comfort and ergonomics
The 20mm eye relief is exceptionally comfortable - even observers who wear glasses can keep them on and still see the entire field of view without dark vignetting at the edges. The fold-down eyecup makes it easy to adjust the eye distance for both spectacle wearers and those without glasses. A filter thread is included as standard - the 2″ filter thread allows UHC, OIII or other astronomical filters to be attached directly to the eyepiece.
Build quality and compatibility
The eyepiece body is built robustly with real field conditions in mind. It is waterproof, so you need not worry about morning dew or light rain. The 2″ barrel ensures compatibility with the vast majority of modern telescopes fitted with a 2″ focuser.

Ideal applications
The Omegon Panorama II 21mm is an excellent choice for astronomers who focus on deep-sky observation - large emission nebulae, open star clusters or sprawling galaxies, where a wide field of view delivers a truly immersive experience. At the same time, thanks to its long focal length and comfortable eye relief, it makes a favourite "starting" eyepiece for survey observations - finding an object with a 21mm focal length and 100° field is quick and easy. Thanks to its compatibility with f/4 and faster telescopes, it meets the needs of the great majority of astronomers, whether observing from the city or under a dark sky.
