Product Info

Manufacturer Description

Vixen's new SSW Ultra Wide eyepieces feature an 83° FOV and 7 element design.  High-reflective and low-dispersion glass, including lanthanum and tantalum, are used in the manufacture of these Japanese made eyepieces. High transmission lens multi-coating over all the lens surfaces in combination with special coating on the lens connecting surfaces deliver high contrast sharp star images across the entire field of view. 100% light volume is evident over the entire 83° FOV with no vignetting even with fast f/4 optics.  This delivers bright images, with no ghost or flare, for an extraordinarily clear field of view. 

  • Anodized aluminum body
  • Unique anti rolling design with hexagonal barrel
  • Retractable eye cup with rubber grip for great viewing and handling comfort
  • Sleeve design is applicable to both screw and compression ring eyepiece adapters

Please note: This is a high power eyepiece that is not suitable for all telescopes or viewing conditions. Before purchase, please research this subject to ensure that you purchase this only if the high magnification this eyepiece provides is feasible and practical for your setup.
