Product description

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 their new look and new internal design, these new Nightsky SWA eyepieces are a far cry from older SWA eyepieces. They are now equipped with higher grip rubber armor and with new eyecups which are not only more convenient but also increase observing comfort.

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.

26 mm eyepieces are 2" models. This means they are ideally suited to deep sky observing and provide enormous true fields of view.

SWA eyepiece series are parfocal, meaning refocusing is no longer necessary when changing between them.


The new eyecup design can be adjusted steplessly, allowing the viewing distance to be precisely adjusted as required. Even spectacle wearers will still be able to see the entire 70° field of view.

The advantages in a nutshell:

  • 70° apparent field of view
  • five elements, in three or four groups
  • blackened lens edges and an effective baffle system for high-contrast images
  • full wide-band multi-coating
  • parfocal within the series
  • steplessly adjustable eyecups
