    Default One Minute FaceOff: TeleVue Panoptic 35mm vs. Baader Hyperion 31mm



    I borrowed the boss's nearly unused, still in box TeleVue Panoptic 35mm eyepiece, 68 deg AFOV, pricetag on box about 600 dollars.

    Before the clouds rolled in, I compared the Panoptic with my Baader Hyperion 31mm, 72 degrees AFOV, pricetag on box about 200 dollars.
    I compared them on some wide doubles like 17 Cygni and Epsilon Lyrae 1 and 2, using the William Optics Megrez 90 apochromat.

    The Baader actually looked better to me. Brighter overall, a bit easier to look into, and believe it or not the edge of field stars were nearly just as bad in the Panoptic as in the Hyperion.

    The Panoptic certainly looks impressive and has considerably more heft to it than the Hyperion, but the eye relief seems about the same, and I find the Hyperion easier to "look into"; maybe this is a difference in exit pupil, I don't quite know how to describe it.

    The clouds rolled in so I didn't get the chance to compare on open clusters or globs, or of course Luna.

    But I score Round One in favor of the Hyperion.

    I think if you look on the used market (check Astromart)you'll find 35mm Panoptics considerably less expensive that that, maybe $250 USD or so, depending.(Telescopes dot com has them for $339 USD new) Baader aspheric 31mm abt ~200 USD.

    TV eyepiece prices have been a bit radical due to the into of the Ethos line and very high quality competition from Baader, Meade, others...

    Did you think the TV eyepiece had a slight 'coffee' tint compared to the Baader? Some folks call that tinting warmth and say that the TV eyepieces are a 'warm' eyepiece compared to others that are neutral.

    Too bad about the curvature in the WO 90, how would you describe the stars nearing edge of field?

    I guess I should have said that's Canadian dollars, from ten years or so ago when the exchange was about 63 cents US to the CDN loonie. And, I now see, purchased from one of the more expensive local retailers.

    So the price differential isn't quite so bad as it seems at first.

    As to the tint....hmmm...my 2 Hyperions always look a bit greenish to me, the 31 less so than the 3.5... I'll have to take another look for that coffee tint in the Panoptic. My main impression was that the Hyperion was brighter overall and had slightly better contrast.
    Even with the small magnification with these two eyepieces I could see the color difference in 17 Cygni even with the wide difference in brightness of the two stars; the Baader showed this difference a bit better than the Panoptic.
    Neither eyepiece was able to resolve the E Lyrae pairs into their A and B components, but at around 20 diameters magnification I didn't expect them to. (The Meade 8.8 UWA and the Hyp 3.5 split these easily in the M90, though.)

    The M90 has a bit of coma around the edges; its color correction is very good, almost perfect at the center of the field and not too bad at the edges, but I have to admit that I was a bit disappointed at the coma appearance of the edge stars in DSLR images. However, the TeleVue flattener/reducer fixed almost all of that.
    Visually, the Meade 8.8 UWA (older production Japanese) that I have gives a very sharp image all the way out to the edges with the M90, but that's not a fair comparison with these longer eyepieces due to the focal length difference.

    It's too bad it clouded up on me, I really wanted to compare these EPs on Luna, which is very bright these evenings. Maybe tomorrow....

    Al great comparison, but if possible, it's better/closer to compare a Hyperion 36mm vs the Pan35 so that the magnification would more or less be the same. I have the Hyperion 31mm, yes it's a great EP!

    Sure, I know, but I haven't got the full line available unfortunately !! So I do what I can with what I've got.
    At least I didn't compare it directly with the UWA 8.8 !! That would really have been unfair.

    I did compare the 8.8 UWA + Ultima 2x Barlow with a 4.5 mm TV Nagler, though... it was pretty sad. The Meade 8.8 gave a more pleasing view even with the Barlow and was much sharper at the edges.

    Wow that UWA 8.8's 4000 series barlowed must be pretty sharp to beat the Nagler 4.8mm T1. The 8.8mm is a partner of the legendary 14mm UWA so it's no wonder. Anyway, might the higher magnification of the Hyp31, thus darkening the background/backdrop contribute to the perception of slight increase in contrast? Factors come into play when comparing un-like EP's, as one forum member would say, it's like comparing apples and oranges, though to a lesser extent.

    Best,

    Hernando
