    Default Vixen NLV vs SLV



    I know Vixen made changes to the body of the eyepiece series when they changed from NLV to SLV, but have no idea about the optics. Does anyone know if there were optical changes between those two series? I am seeing some NLV eyepieces for sale and am curious about them vs the SLV series.

    NLV has narrower FOV (45 deg vs 50 for SLV). Other than that I suspect that they would behave similar.

    Thanks Bigzmey! That is the kind of information I was looking for!

    As I understand it, the NLVs have a 45 deg FOV in the shorter focal lengths, but the rest are 50 deg. With the SLVs, they're all 50 deg. Other than that, they're pretty much the same.

    Thanks! Keeping a 50 degree field is important to me, so that answers a big question.

    Hello Bill, missed this post earlier.
    The SLV also has better coatings and in my f/8 Achro the 4, 6 and 9mm were great.
    I would even venture to say that they are creeping up to the LVW quality of view.

    The SLV's are like hi-grade plossls, big eye lens and more eye relief. I've got 2 a 10mm & 12mm. Wished they had made'em 60 degree, then they would be perfect.
    Newtman but some refractors allowed.

    Thanks, Tom! I think they are made mostly with eyeglass wearers in mind, but having the longer eye relief is nice in the shorter focal lengths. I, however, have trouble going for the "big bucks" needed for eyepieces like that for my little entry level scopes that I have "tuned up." For the most part, I am very happy with the NPL series I have. Personally, if they dropped the 4, 6, and 40mm, then added a 9, 11, and 12mm to what they have, it would pretty much be the perfect set.

    With the SLVs, the pretty much have that, but at a significantly higher cost.
