Omegon SWA 20mm Eyepiece, 1.25

The Omegon SWA series represents a new milestone in super wide angle eyepieces. These new Omegon SWA eyepieces are a far cry from older SWA eyepieces, with their new look and new internal design. They are now equipped with higher grip rubber armour and with new eyecups which are not only more convenient but also increase observing comfort.

Super wide angle eyepieces have long been held in high regard due to their extremely wide apparent fields of view. Only with SWAs did the so-called 'space walk' effect - almost like the view through a spaceship window - become reality. In the optical department, there are now five glass elements arranged into three or four groups depending on the focal length involved. These give a 70° apparent field of view with high edge definition and a virtually distortion-free image.

The human eye can still easily take in a 70° field of view without having to 'look around' in the eyepiece. These eyepieces can also be used with relatively fast, short-focus systems. A new wide-band multi-coating means that light transmission has been increased even further. All lens edges are blackened and the internal baffle system reduces scattered light even further. Only high transparency glass surfaces and reduced reflections can ensure a really high-contrast image.

The Omegon SWA series consists of six eyepieces: 38mm, 32mm, 26mm, 20mm, 15mm and 10mm. The 38mm, 32mm and 26mm eyepieces are 2" models. This means they are ideally suited to deep sky observing and provide enormous true fields of view. The shorter focal lengths: 20mm, 15mm and 10mm come with a 1.25" barrel.

These powerful eyepieces are designed for fast telescopes. Their new design and improved features make them a significant upgrade over older SWA eyepieces. The combination of a wide apparent field, high edge definition, and reduced scattered light results in a truly immersive and high-contrast observing experience, even with short-focus telescope systems.
