    Default Vixen Eye Piece Code Letters



    Having a Vixen scope, I'm on the mail list for the importer. Today I got an email advising of a sale on their lenses. Most excellent discount. But I don't know how to choose. They are 82 degrees and are SLV and SSW. That's the confusing part. Can someone provide some info on just which to buy. Thanks. Just FYI, there IS a youtube video on how Vixen scopes are manufactured.

    The Vixen SLV is a 50 degree AFOV, 7 element eyepiece which offer around 20mm eye relief. The SSW is an 83 degree AFOV, 7 element EP which has around 13mm ER. I've never used one of the SSW's, but they are said to be the Vixen version of the Nagler design by TeleVue.

    The various "LV" series have usually been 50° step up from the Plossl with 20mm eye relief, the "W" is the widefield 80° in this case, 65° for the old LVW series.
    Vixen coding can be fun to keep track of at times.
    Refractors: Antares 105 f/15, Bresser 102 f/13.2, Celestron 102 f/6.5, 2-150 f/8, Stellarvue 80 f/6.9, TS 102 f/11, Vixen 115 f/7.7
    Mounts: Manfrotto 055PRO, Celestron SLT, Celestron CG-5/ Argo Navis, Vixen SXP Binoculars: Celestron Eyepieces: A-Z

    The weakest link in the optical chain is the large nut located directly behind the eyepiece/ camera. - Gabrielle

    Ric,

    I have the 14mm SSW. Freaking AWESOME eyepiece!!!

    I've used it in an ED80 refractor, a 9" f/12 Mak, and an 8" f/4 Newt. Sensational in all three scopes!

    In the very fast Newt it is most surprising. Yes coma is visible, but it is most mild and you need to go looking for it at the edge of the FOV. I didn't use a coma corrector as this way I get a true feel for the eyepiece neat. I now just don't bother with a coma corrector with this eyepiece and my f/4 Newt.

    In the refractor and Mak it is flawless. In the ED80 I examined the full Moon, and was astounded by how many stars it showed surrounding Luna! Something I just cannot say I've ever really noticed before!

    A friend of mine also has the 14mm, and recently picked up the 10mm. He's only used it in his 9" Mak and refractor, in which it is also a cracker, but we haven't tested it in a fast Newt just yet.

    Mind you, my post is ONLY regarding the 14mm in three different scope types, and the 10mm in a frac and Mak. I cannot speak for the other focal lengths in the series, and you shouldn't make any assumptions about them based on this limited review. Each focal length will perform differently, especially in a series primarily designed for refractors, Newt performance can be very different.

    Alex.
    It's me, down to the last rusty bolt.

    The Vixen eyepieces are excellent performers and as SpyderwerX has said, each line offers specific performance traits and optical characteristics. If the prices reductions are significant, they are worth a close look because the main reason that they are not more widely distributed and sold throughout North America is only because the are generally more expensive and less aggressively promoted than the competition. If this was the pricing that you were offered on the SLV line - https://www.vixenoptics.com/category-s/159.htm - they are worth considering.

    The Japanese market is very competitive with many high quality offerings, but their products often end up neglected because the lower priced Celestron, Meade, or Explore Scientific models offer nearly as good performance levels at much lower prices and folks looking for premium performance frequently skip past them to pay even more money for the best German and American models. Pentax is the only company that seems to make an effort to compete on this continent, so we don't see much of the Vixen, Nikon, or Takahashi models to form our own opinions.

    These links may help you to decide whether to look into them further:
