    Default Saturn is spectacular, and so are Antares Plossl eyepieces



    Due to a combination of either working, or the generally horrible N/E Ohio
    weather, last night was the first time I've gotten out to see Saturn in
    nearly a year. All I can say is that (being as large and close to us as
    it is right now) it is absolutely stunning! If you haven't seen it yet
    this year, don't miss any opportunities to do so soon!!!

    Viewing was done with my home built 13.1" F/5.23 truss Dob. My standard
    eyepiece fare is my 14mm, 8.8mm, and 6.7mm Meade UWA's, and they
    absolutely did not dissapoint in the least (alone or coupled to my 2.5X
    Powermate). The views through the 6.7mm UWA (which I often boast as my
    planet-killer eyepiece, a view I share with none other than Todd Gross)
    were stunning. My opinion of the UWA's is that they are exceptional
    eyepieces, rivaling (and often besting) the Nagler lines.

    However, on this night I also made good use of my very inexpensive 25mm,
    20mm, and 15mm Antares Plossl eyepieces in conjunction with my 2.5X
    Powermate and 3X Antares barlow. These are the 'premium' Antares 5
    element (super) Plossl's, often (mistakenly?) referred to as Antares
    Ultimas, or as Antares Ultrascopics. The Antares are outwardly (at least)
    identical to Orion Ultrascopics, and are 100% parafocal with them as
    well. In the past I had compaired my 15mm Antares with a 15mm Orion
    Ultrascopic, and the only difference noticed (in daylight) was a slightly
    different multicoating hue. Views through the scopes between the two of
    them were (to my eyes, and those of a viewing friend) indistinguishable in
    an extended swap test on multiple subjects, including Mars at near its
    closest approach. The Antares Plossl eyepieces (all of which are
    generally to be had for ~$69 US new, mine having been bought used at $45
    each on Astromart) are truly exceptional bargains. When used with my 2.5X
    Powermate and/or 3X Antares barlow, they gave tremendously tack sharp edge
    to edge views of Saturn which were comparable to the views in the UWA's,
    except only in AFOV. In fact, the eyepiece of the evening was the Antares
    15mm with 2.5X Powermate (6mm effective FL, yielding 290X). Absolute
    Saturn perfection, the likes of which I can't recall ever seeing better
    before (with before in my case extending all the way back to 1982)! I
    didn't think it possible for the budget Antares to give a better view of
    Saturn than that of my 6.7mm UWA, but it did, mainly in giving a bit more
    magnification and revealing more band and ring details by virtue of its
    higher magnification. This combo must have hit both my exit pupil sweet
    spot and the prevailing sky conditions dead on last night. In fact, I
    perceived both sharpness and contrast to slightly favor the 15mm
    Antrares/Powermate combo, despite the higher magnification!

    I Lawrence,

    I will check Saturn this night since a good weather was annouced for Quebec. I
    will use my 12,5 F6 dob with Speer Waler Eyepiece 7mm and Nagler 12,5.

    ;-)

    Saturn will be closer on 12/31 than it will get for the next 18 years or
    so. Your setup and eyepieces should give excellent views indeed! Also,
    your Speers-Waler comment just reminded me. I'm still trying to figure
    out if the new Speers-Waler WA series eyepieces (the relatively new ones
    with 80 degree AFOV's) are good values for the money or not. I've
    considered picking up the entire series (18mm, 14mm, 10mm, and 7.5mm) to
    test head to head with my Meade UWA's, but I generally like to hear at
    least some comments from users first. They are said to have fixed the
    focuser in-travel issue in Newts with this eyepiece series. The strange
    silence surrounding this new series of eyepieces (out for about a full
    year now) is deafening.

    Odd you should mention that (those) particular eyepiece combination(s).
    I have bought and tried about _every_ eyepiece made for under $200,
    including TV Plossls, Celestron Ultimas, Tak LE's and others. The
    absolute BEST views I have ever had always come back to the Antares
    Plossls in 25mm, 20mm and 15mm, either singly or with a 2.5X Powermate
    for power and retaining eye relief. The Orion Ultrascopic and the
    Antares Plossls ARE the same, and even though "made in the same
    factory", the Celestron Ultimas are NOT the same in design as the
    Antares and Orions. The Celestrons have a slightly smaller AFOV and LESS
    eye relief on a proportional basis. The Antares/Orion Plossls even had
    less "ghosting" than the UO Orthos. My views with these eyepieces were
    mostly with my 8", f/6 Newt and 10", f/6 Newt, both with Mike Spooner
    mirrors, Protostar secondaries and old eyeballs.

    who sells these at reasonable prices , please post some links to web
    vendors. Also, does Antares have a website with their products ? I have some
    other Antares products and while the aesthetics are influenced by cost
    control, they seem to be reliable performers , or better said, a lot more
    performance and more solid engineering than one would expect for the money.

    Thanks,
    Matt

    The best current 'US' prices (I've found) for new ones are at either
    'Hands On Optics", or 'Meridian Telescopes'. Here are the links:

    http://www.meridiantelescopes.com/deteyepc.htm

    They are also available at 'Island Eyepiece', 'O'Neil Photo and Optical',
    and many more outlets in Canada, the US, and all across Europe.

    I've never seen an Antares web site.

    Thanks for your advertisment, Saturn was a beautiful spectacle last night. I
    Appeciated de big field of my eyepieces

    My Speer Waler are 7mm and 18mm and the two have 82Deg field. With the 7mm at
    283X, Saturn presented superb details but at 166X with my Nagler 12mm the
    seeing was more stable.

    I saw the Cassini division, the Enke division the equatorial band and polar cap.
    I saw Titan and I think, Japet and one other satellite. Is it possible ?

    I dont know about the new series of Speer Walers. The links is:

    Hi there. You posted:


    Yes, it is possible to see many moons in a 12.5 inch (probably anywhere from
    four to six, including Iapetus). However, I doubt that at only 283x you
    actually saw the Encke Division. It takes something in excess of 350x to
    clearly separate it from the outermost edge of the A-ring. You may have seen
    the darkening of the outer half of the A-ring, which is often mistaken for a
    division. Try putting in a decent Barlow and try again (I like the TeleVue
    2.5x Powermate). Clear skies to you.

    Hi there. You posted:


    Well, a true Plossl is a 4-element eyepiece, while the Orion Ultrascopics use
    5 elements, so they are different. The Antares may be called "ultra-Plossls"
    if they use more than 4 elements (Meade used to sell their 5-element designs
    with the name "super-plossl"). The Celestron Ultimas are an almost identical
    design to the Ultrascopics, as both use 5-elements and have similar
    characteristics. Clear skies to you.
