    Question Mystery EP



    I got this EP included as an appreciation gift for ordering a clamp set for my SW SkyTee2. Nice touch

    The sticker says K20mm. So I assume Kellner 20mm? It seems to have single layer light blue coating.

    Anyone can ID it? Once I get to the office on Monday I will try JG's laser trick.

    Definitely a Kellner, if the lenses are decent glass it should not be a bad eyepiece with your SCT and might even give some moderate views in the 127mm.
    AFOV will probably be somewhere between 45-50°. It may be a good outreach eyepiece if nothing else.
