Omegon SWA 20mm eyepiece, 1.25''

The Omegon SWA series marks a groundbreaking advancement in super wide-angle eyepieces.

Renowned for their exceptionally wide apparent fields of view, super wide-angle (SWA) eyepieces have always captivated observers, offering an immersive "space walk" experience akin to peering through a spaceship window.

Enhanced Design for Superior Performance

The latest Omegon SWA eyepieces boast a sleek new look and upgraded internal architecture, setting them apart from their predecessors. Featuring improved rubber armor for enhanced grip and redesigned eyecups for heightened comfort, these eyepieces elevate the observing experience.

Optical Excellence

Incorporating five glass elements arranged into three or four groups depending on the focal length, the Omegon SWA eyepieces deliver a remarkable 70° apparent field of view with exceptional edge definition and minimal distortion. Designed to accommodate relatively fast, short-focus systems, they ensure an immersive viewing experience without the need for constant adjustment.

Advanced Coating Technology

Equipped with a new wide-band multi-coating, these eyepieces achieve even higher light transmission, resulting in brighter, clearer images. Blackened lens edges and an effective internal baffle system minimize scattered light, ensuring high-contrast views with reduced reflections.

Versatile Selection

The Omegon SWA series comprises six eyepieces: 38mm, 32mm, 26mm, 20mm, 15mm, and 10mm. While the 38mm, 32mm, and 26mm variants feature 2" barrels ideal for deep-sky observation, the shorter focal lengths (20mm, 15mm, and 10mm) come with 1.25” barrels. All eyepieces are parfocal within the series, eliminating the need for frequent refocusing.

Customizable Viewing Experience

With a newly designed steplessly adjustable eyecup, users can fine-tune the viewing distance to their preference, ensuring optimal comfort for both spectacle and non-spectacle wearers. Spectacle wearers can enjoy the entire 70° field of view without compromise.
