Vixen’s SLV Series eyepieces feature fully multi-coated lenses in a full metal body. High quality lanthanum glass with a scratch resistant lens surface delivers an exceptionally clear, high contrast field of view. With comfortable long eye relief of 20mm, improved twist-up eye cup for adjusting the best eye-point, and high eye point design, you can use these eyepieces for many hours of observation without eye strain. The unique shape is easy to grip and the polygonal rubber grip provides anti-rolling protection.

Vixen SLV 4mmPros: Cons: Comments:
The eyepiece has some very nice features. The twist-up eyecup is well designed and implemented. The smooth eyepiece barrel also makes it easy to insert and remove from focusers and adapters. The image quality is first-rate, but the AFOV is a little tight. Overall, an excellent eyepiece. Definitely recommended.

Excellent. Sharp images and comfortable to use.Pros: Cons: Comments:
The Vixen 4mm SLV eyepiece is excellent in terms of performance and comfort in use. Images are sharp and color free, light scatter is absent and the 50° field is plenty for lunar or planetary observation. Contrast is high and color fidelity very good. The eye relief is comfortable and eye position not super critical. It is as good or better than any short focal length eyepiece I've used.

Checks all the boxesPros: Cons: Comments:
I added this 4mm SLV to my collection to maximize magnifications using f/5 scopes. Like other SLV's that I own, this eyepiece offers long eye relief and has excellent fit and finish. I have used it recently to view double stars with a 80mm f/5 refractor and 203mm f/6 dob. Images were bright and sharp. The SLV line is worth every penny, particularly now on sale. This eyepiece does not disappoint.
