    Default Baader Hyperion and SCT?



    Hello folks.😁 i have an old 79 model C8 and was looking at the baader Hyperion's. Anyone using a combo like that? What do you think of the pairing? Thanks!

    The Hyperions will work well in the f/10 SCT, or in a Mak. But if you decide to get a fast Newt, it will be horrible in it and not much better in a short fast refractor. Frankly, I'm not a big fan of them because I have many scopes and they just don't perform well in most of them (I sold all of mine off to fund other EPs). I much prefer the ES offerings for wider angle EPs including use in the SCTs and Maks. Or for a more moderately priced 60 degree EP, I like the Celestron X-Cel LXs.

    The Hyperions work well with the slow focal ratio of the SCT, and the wide apparent field of view and long eye relief are nice - and if you're into fiddling you can tweak the focal length with spacer rings.

    You might also want to keep an eye out for used Vixen LVWs - the form factor, eye relief and AFOV is similar, but the optics are different - I much prefer the LVWs. I _like_ the LVWs (in my fracs as well) while I can take or leave the Hyperions; For some reason, I just get on a lot better with the LVWs. Keeping an eye out for used ones should bring the price closer to the Hyperions; the LVWs are more expensive new.

    Eyepiece choice tends to include a large element of personal preference - your mileage may vary . Also, some eyepieces work better with particular scope types - the focal plane of most scopes isn't actually flat, and different scope designs can curve in opposite directions. Also, fast scopes (low f-ratio numbers) tend to be more demanding on eyepieces, since the light arrives over a wider angle. The good news is that at f10, SCTs are relatively slow scopes, and most eyepiece designs will tend to work well with them .

    Hello Rick-o,

    the Hyperions have been originally designed both as the visual and as the afocal photographic eyepieces,
    with the optional fine tuning rings to adjust the magnification and field framing in small steps.
    I used to have the full set of the Hyperions together with the fine tuning rings,
    but the problem has been their lower contrast performance if compared with other eyepieces from Baader.

    It may be also the case, that they have been better field corrected for the refractors than for the fast mirror scopes.

    As I don't have a SCT, I can't say how the Hyperions would compare with the other eyepieces on SCTs.

    Best,

    JG

    I would agree with Jerry and JG, compared to my Vixen LVW the Hyperion though good were not a match for the LVW.
    Baader normally makes excellent eyepieces but the Hyperion did not suit me.
    If you do not mind buying used I would look for the LVW instead.

    Thanks guys i'd love some vixins but the budget wont allow. $150 is where i top out. I'll look into the celestrons for sure. I like the wide coverage and good eye relief. The imaging was a plus for my nikon. But i'll fine a way.

    Depending on which focal lengths you wish for first they do come up regularly on the used market for $125/150USD

    All zoom eyepieces are always a compromise but the Baarder Hyperion is less of a compromise. Lets look at the specifications :
    Between a focal length of 8mm to 24mm you have eye relief of 19mm to 16mm : having a eye relief of 16mm on a 24mm eyepiece is good, having 19mm on a 8mm is great! at the same time you got a apparent field of view of between 68 degrees and 48 degrees, and here is the compromise : AFV of 48 deg. on a 24mm eyepiece is not great but 68 deg on a 8mm eyepiece is.

    So to summarise you are covering 8 to 24mm eyepieces with a bit of a AFV compromise at 24mm at the same time the sharpness of images is just slightly less than my TeleVue Nagler eyepieces at the same FL.

    PS : maybe I haven't said it clear enough:
    Consisting of 7 elements, the Hyperion optical design delivers outstanding sharpness and color correction over its wide flat field, even with fast telescopes and is only outperformed by high quality dedicated eyepieces.
