    Default Panoptic 24mm wins



    On Wed, 17 Sep 2003 11:13:57 -0700, "Doink" <lancha@ix.netcom.com>
    stepped up to the plate and batted:


    The Panoptic line of eyepieces by TeleVue features a 68 degree
    apparent field of view and are reputed to be "tack sharp" accross the
    whole field of view. They are preferred by many over standard plossls
    because of the higher mags you get for a given FOV while retaining
    a sharp field all the way across.

    If there is something in the above statement that you're not familiar
    with, stop right now and hold on to your money.

    The 24 pan goes for 295$ and for that kind of money you can get a set
    of decent eyepieces of a different desing

    From your original thread:


    What kind of eyepieces do you already have? What do you define as a
    "small field of view?"

    The panoptics aren't so hot if eye relief is a consideration for you.

    For a good, all-purpose low power eyepiece with adequate eye relief,
    you can't beat a good 32mm plossl.

    The price you pay for that tack sharp fov is some pin coushion effect. That
    is, the image is distorted toward the edges. I took my 24 Pan out for
    daytime viewing and pointed it at a road sign nearby. The post was severely
    curved when you put it about 75% of the way out towards the edge of the FOV.
    This manifests itslelf as a curved image when you are panning around at
    night in a star field. Some find it annoying, I do not. Wouldn't want to
    use it for terrestrial viewing , though.

    Clear skies,

    I have built ep's with a severely curved field on the edges when held over a
    piece of graph paper, but they don't give curved images.

    I'll through in my $.02...

    I recently jumped on the TV EP bandwagon after spending countless
    dollars on "bargain" eps. There are some decent ones out there, but my
    experience was that as I developed my oberving skills, I became more
    annoyed by the narrow fields of view, and the fuzzy, distorted stars
    at the edge of the field. I came to the realization that it was better
    to own a couple of really good EPs than a case full of so-so ones. I
    now own:

    9mm UO Ortho
    13mm Nagler
    19mm Panoptic
    24mm Panoptic
    35mm Panoptic

    Now that is a few bucks of glass, but here is another point. I bought
    all of these used on Astromart for about 65%-75% of their retail
    value. They are all in superb condition, save for a few set screw
    marks. However, two years down the road, I'll bet you that I could
    sell them for close to what I paid for them, if I take excellent care
    of them. My experience in selling my other eps is that I am lucky to
    get 50% of their retail value, even in excellent condition. Consider
    this very carefully. If you have the $$$, by the 24mm Pan. BTW, I am
    aware of the pincushion, but I have yet to notice its effects in the
    dark. I don't do daytime observing.

    Matt,
    Same here wrt reasons I splurged on eyepieces. What are your thoughts on
    owning both the 19 and the 24 Pans? I selected the 24mm to complement the
    35mm. For a time I was considering the 27mm, with the 19mm as a complement.
    If I had it to do over, I might..., ermm..., well..., anyway I'm not really
    unhappy with my final choice. Just curious if you find you use them both a
    lot in the same session, or if one tends to see significantly more use than
    the other.

    (I actually need to go up a notch and get a 5mm before I fill anything in
    below, but the 19mm has its allure for use with the 8' SCT.)

    > Matt,
    complement.
    really
    than

    Stephen-

    I use the 19 more on Globs and the 24 with a UHC filter on nebulae. The
    wider field without the need of buying 2" filters is nice. The 35 is great
    for extended galaxies, nebula and especially star clusters. The Pleiades
    (sp) is unbelievable. I don't feel that the 13mm Nagler and the 19mm pan are
    redundent as suggested in an earlier post. They are about .15 degree
    difference, which doesn't sound like alot, but its about 112% more total
    field in the 19. The 13 is great for small, bright GCs like m15, as well as
    planets and luna. I have kicked around getting a 27mm Pan to fill in the gap
    I have between 24mm and 35mm. There is about a .36 degree gap there, or 168%
    more field in the 35mm. Or maybe I should save up for a 26mm
    Nagler....yummy!

    Matt
