SWA 2inch 38mm Super Wide Angle 70 Degree Eyepieces for Astronomical Telescope - Five Elements Fully-Coated High-Index Glass - Blackened Internal Baffle System

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.
With its new look and internal design, the SWA eyepieces are a far cry from older SWA eyepieces. They are now equipped with an easier to grip rubber armour and with new eyecups, which are not only more convenient but also increase observing comfort.

There are now five glass elements arranged into which give an apparent field of view of 70° with high edge definition and a virtually distortion-free image. The human eye cans still easily take in a 70° field of view without having to change the view in the eyepiece. They can also be used with relatively fast, short-focus systems. A new broadband multiple 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.
A large selection of 2" and 1.25" eyepieces.
The SWA series consists of 5 eyepieces: 38mm, 32 mm, 26 mm, 20 mm, 15 mm and 10 mm. The 38mm, 32 mm and 26 mm eyepieces are 2" models,which are ideally suited to deep sky observation . The shorter focal lengths: 20 mm, 15 mm and 10 mm come with a 1.25" barrel.
