    Default Pre-Review: Paul Rini 30mm EP (65° AFOV)



    I've been looking for the widest true field I could find in a 1.25"
    eyepiece for my binoviewer, and I noticed that Paul is advertising a
    new series of eyepieces at astronomy-mall.com. The 30mm is described
    as having a 65° apparent field. I contacted him and found out that the
    clear aperture of the field lens is 28mm (maybe a little more in
    reality as the barrel is only 1mm thick and there's no field stop),
    the lends are coated with magnesium flouride on all air-to glass
    surfaces, and the lens edges are blackened. So I ordered a pair - at
    $29 apiece, they are not expensive.

    They arrived yesterday. They are black, with "Paul Rini 30mm" stamped
    in the black metal barrel. They come with lens covers top and bottom,
    look very professionally made, and are threaded for filters.
    As I did not have much free time last night, I set up a 90mm ETX and
    slipped one of these in to the eyepiece holder. I just had a quick
    view of the moon. At f/13.9, the eyepiece was literally sharp to the
    edge. I noticed that you had to move your eye around to get the entire
    field of view (the eye lens is over 1.25" in diameter) and I'd say
    that the apparent field is a bit greater than advertised. But I think
    that the baffling in the ETX may have vignetted the field a tad.
    Contrast was very good, as the sky qppeared quite black despite the
    lunar glare.

    I hope to provide more feedback on these in 10 days or so, but they
    appear to be very promising.

    Clear skies,

    Hi Shneor,
    If you would, in your upcoming review of these eyepieces, please keep in
    mind your impressions of the WideScan III. I'd like your thoughts on their
    similiarities, if any, as far as edge performance. I have experience with
    the WS3 so the comparison has relevance.

    Thanks,
    Stephen Paul
    Shirley, MA

    Hi Stephen,
    I have a Widescan II (with blackened lens edges), but I expect it's
    otherwise optically identical to the Widescan III. But the Rini is a
    1.25" eyepiece, not a 2". I hope to be observing September 11 - the
    views then will be using a Denkmeier binoviewer through an f/4
    (effectively f/5 with the 2" OCS).

    Clear skies,
    Shneor

    Something does not add up -- or should I say multiply. The field
    stop of a 30mm EP with a 65-degree AFOV needs to be slightly under
    1.5 inches. It is physically impossible to do that in a 1.25-inch
    barrel.

    Hi:

    Dunno, but I _always_ enjoyed his dirt cheap but effective eypieces, especially
    the 2 inchers. The Chinese have _yet_ to catch up to Paul in this realm.

    Healthwise, Paul is doing a lot better I stopped over to see him about
    3 months ago, and he is the one doing the eyepieces etc. Have known
    Paul for a number of years, never met or new he had a son. Clear
    skies, Bob Midiri

    HI Bob:

    Next time you see him, remind him how much many of us have enjoyed his
    eyepieces over the years, and how glad we are to see him back in the game.

    I'll second that! I've only ever owned his 2" 38mm Modified Plossl, but
    I enjoyed using it a great deal, and it was a great value for the $$$.
    Optically superior to the 30mm Wide Scan II and the 30mm 1rpd, for (as I
    recall) $46.
