Omegon SWA 26mm 70° 2″ eyepiece
If you are looking for an eyepiece that offers truly comfortable and optically uncompromising observation of the night sky, the Omegon SWA series ranks among the best choices in its class. The model with a 26mm focal length and a 70° field of view delivers an impressive sweep of the sky - ideal for exploring large open star clusters, nebulae and the expansive star fields of the Milky Way. Its improved design and internal optical construction place it well above comparable models from other manufacturers.
Optical construction
The eyepiece consists of five optical elements arranged in groups of 3 or 4 elements depending on the focal length. This construction ensures a well-corrected image across the entire field of view with no significant aberrations at the edges. A key feature is the new broadband FMC coating (fully multi-coated) applied to all optical surfaces, which significantly increases light transmission and preserves the natural colour fidelity of observed objects. The edges of all lenses are blackened, effectively eliminating unwanted internal reflections and light scatter inside the barrel. The result is a high-contrast, sharp image appreciated by both beginners and experienced observers who demand precise optics.
Design and ergonomics
The entire body of the eyepiece is covered with a protective rubber layer that shields the optics from impacts and provides a firm, comfortable grip even in cold night-time conditions. The newly designed rubber eyecups with adjustable height allow comfortable observation both with and without glasses - clearly designed with long observing sessions at the telescope in mind.
Compatibility
The standard 2″ barrel diameter guarantees compatibility with all telescopes equipped with a 2″ focuser. A 1.25″ reduction ring is included for broader usability across a wider range of telescopes.
Who is this eyepiece for?
The Omegon SWA 26mm is an excellent choice for anyone who wants a panoramic view with comfortable eye relief and a wide field of view. It works perfectly as a first low-magnification eyepiece for overview observation, but its optical quality will also satisfy more demanding observers. Whether you are scanning large deep-sky objects or simply enjoying the Moon in its full glory, this eyepiece will do an outstanding job.
