    Alex-
    If both F. and C&P checked it out your SNO-T, what exactly did they check? How?
    As against what didn't meet the specs? I would expect there are many avenues for
    error (such as imprecise or uneven engraving or division on the arc) that they
    wouldn't check for.

    I had thought you were happy with the instrument, didn't realize it wasn't
    meeting the specs it was rated for.

    I can't tell you how to have confidence in the quality of any new or used
    instrument, at some point you take it on faith backed up by some type of
    warranty from the seller.

    I have an old pair of Zeiss binoculars that use similar filtering, a pair of
    "tobacco" colored inserts in screw-in rings for the eyepieces. You might try to
    contact Tiffen or another photographic filter maker. If you can give them the
    pitch and diameter for the threads (either measured or researched) they might be
    able to supply you with something reasonably. As a temporary kludge, I would
    suggest a trip to an auto parts store and $5 spent on a foot of cheap "window
    tinting" material. I know, it won't be optical quality <G> but you should be
    able to put a tiny spot of it in the eyepiece to get a temporary tint that would
    le you do some sun sights whilst waiting for a better solution.
