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

VIXEN SSW 7mm eyepiece
Pros: Cons: Comments:This one fills the gap in my eyepiece set(35mm, 22mm, 14mm, 10mm, 7mm, 5.5mm, 4.7mm, 4mm) used with a 12" f/5 truss-dob. I also own the 14mm and 10mm SSW's to have some parfocal ep's in the middle range of magnification, which IMO is the most frequently used for DSO's. The SSW's do have some kidney beaning if you don't adjust the eyecup in the right position before observing. But nevertheless they give very sharp and crisp views over estimated 90 percent of the field once you did it. Another point is the short eye relief of 13mm which isn't sufficient to use with eyeglasses, what don't bother me as i'm using contact lenses. Overall in my eyes their advantages (size, weight, twistable eyecup, optical performance) outweigh their disadvantages and make them real keepers to me.
