    Default Baader Eyepiece types question



    I have a couple of Baader Hyperion 1 1/4 EPs and a 2" 76* Baader Aspheric 36mm. I've only found the names in a couple of places but no info. They seem to be common but would like to know the difference.

    My nutshell understanding of this is that regular eyepieces use spherical lenses, and the aspherics use an aspherical lens construction. Using an aspherical lens allows the manufacturer to better control normal eyepiece aberrations using fewer elements than with spherical lenses. However, the trade off is that producing an aspherical lens is more difficult with less room for error in the process. Hope that helps.

    Hello Ricford,

    the 2" Baader aspheric eyepieces are modified Erfle with an acryl moulded asphere to correct the field curvature.
    The Hyperions have a design derived from the Vixen LVW, and they are the budget versions of the LVWs.

    There is a short read on the EPs with a mass of truth, and free from the marketing promotion buzz, by Sven:
    Okulare , a guy, who has really had all these EPs he is writing about, and not just had heared about them. It is written in German, so run a translator on the text.

    I have had the complete Baader Hyperions line, and have sold all of them.
    I have had 1 EP from Vixen, and sold it as well.

    Hoping, this helps,

    JG

    At one point I read on Baader website that Baader Hyperions are also Erfles with added front lens. So, both lines are based on Erfle with different extra elements added.

    I did not actually know in fact but just 'thought' they might not be something that I'd want. I hardly ever used them. They'll soon be for sale at a bargain price. I'll convert to either ES or Televue and move on. I have one ES now as a start. I'd like a few good quality lenses. I just bought that Baader aspheric from OPT two weeks ago and have not used it. Perhaps I can return it. Thanks for the info. I didn't know until now. I'll correct it. I read and speak German so at least that worked out.

    It is not like Hyperions are bad. They are discent EPs, but of older design and are outperformed by other EPs like ES 82 and 68s. But I do like Baader Aspheric. They perform nicely as low power 2" EPs in my scopes, good combination of light weight and performance. There are better corrected 2" EPs out there of cause but they just too big and too heavy (over 2 lb) for my taste.

    Hello Rickford,

    the problem is, we all are herding the eyepieces like chicken, http://www.astronomyforum.net/member...eyepieces.html , aargh!, I have forgotten to add the new Pentax XW 3.5mm to my album, sorry.
    But anyway, that's much less than I used to have.

    I have been more consequent with the set of my clubs:
    Tomorrow I'll take the Bettinardi putter, sand wedge, two Caalaway irons, and one light King Cobra wood 4R, definitely enough for the 9 holes course.

    Best,

    Hyperions are awful if you have an f/5 scope. The outer 1/3 of field is out of focus. Even the Aspherics have large edge problems. The new Morpheus still has the outer edges out of focus. They probably all work ok in f/8 scopes. The only thing from Baader that was any good were the old Genuine Orthoscopics. But then they screwed those up when they went to China with the Baader classic orthos.

    The Baader zoom and their 2.25x barlows are the only eyepieces worth buying.

    That's sad to hear as the only orthos I own are a couple of the BGOs, they're quite good. Too bad they changed.
