    Default Is there a good reason to upgrade



    Hi I currently own the following Baader Hyperion ep's
    5mm 68 degree fov
    8mm .....
    13mm .....
    17mm .....
    21mm .....
    24mm .....
    31mm 72 degree fov
    36mm .....
    I use these with an 8inch sct for mostly visual observing and if doing deep sky I also use an f6.3 focal reducer.
    I was thinking of upgrading to the explore scientific 82 degree ep's. My reason being I feel I would like to cut down the amount of ep's in my collection because at the moment I'm forever swapping ep's when viewing, also I quite fancy the larger fov.
    Could I please have your thoughts on this upgrade and if it really is worth the effort.
    Many thanks.
    Scope = Celestron CPC800 8"sct. Sky-watcher Heritage 130p flex tube Dobsonian Binoculars = Helios Ultima 10x50 porro prism.
    Eyepieces = Baader Hyperion Aspheric 31mm and 36mm. Baader Hyperion 8mm, 13mm, 17mm, 21mm and 24mm.
    Diagonal = 2" Altair dielectric diagonal.

    I really like my ES 82s, they are my most used EPs. If you like the wider views, you will like the trade. But your biggest benefit is if you ever decide to get a Newt or a fast refractor. The Hyperions will not perform well with those scopes, the ES will perform very well with those scopes as well as the cassegrains you now have. They are very sharp to the edge in my SCTs and Mak.

    The ES 82's are nice eyepieces.

    Not sure if they will attain your goal of mitigating eyepiece swaps. I do this constantly while observing, though, for the most part, it is between 2-3 eyepieces. Sometimes more, depending on the object, its altitude, the scope I am using, etc.

    Do you have a friend or a fellow club member that might loan one to you for a night of observing?

    Not sure it'd help any in cutting down the number of eyepieces. I usually end up swapping between three most of the time, but if you're using more, then I don't know if having a wider AFOV will change that much. While a wider AFOV lets you fit more in at a given magnification, so you might not need to drop to a lower magnification to fit something in, it depends on your observing style as to whether that would make a difference. If you want to keep filling a similar fraction of the FOV, you'll probably still want just as many eyepieces .

    I consider my eyepieces as tools. Much like my mechanical tool boxes at work, I have many of the same size but designed for different purposes, and of different brands. EP's are much the same. Although you may only use one every now and then, it is great to have it for when the need arrizes. A full set of a specific line or brand is nice also. If they are paid for might as well keep them. With your particular focal length scope the Hyperions should perform just fine. Replacing them with larger FOV EP's may be in order but useful only in the low magnification focal lengths to really take advantage of the extra few °'s afforded by them. As you increase magnification the FOV becomes less of a concern as the point is to zero in on a specific region or object.

    I have a couple of Ethos EP's of 10mm and 8mm. I very seldom use these. I use my 12mm Nagler T4 as my preferred EP over the 10mm Ethos. Eye relief is better and the FOV seems just right. The 8mm Ethos is hardly ever used, but it is there just in case of the perfect night when things are just right. They are paid for so why get rid of them. I am finding more and more that I prefer a 65 to 82° FOV to be optimal for my viewing preferences. The 100° fields are just to much. In hind sight I should have waited for the introduction of the Delos line.

    I don't know that swapping a 70 degree afov for an 82 degree is much of an upgrade in itself. To my way of using eyepieces what you are missing is lower magnification and larger exit pupils. Heck you can only get a 3.6mm exit pupil with your lowest power ep. I want something like a 5mm exit pupil for difficult large DSOs on excellent nights. To that end I have 50mm fl eyepieces that I use a lot then, my Horsehead Nebula eps.

    My favorite is the Takahashi
    https://www.landseaskyco.com/takahas...-eyepiece.html

    Its optical quality is superb although the afov is only 50 degrees so you'd get the same true fov as the Baader 36 about. But it would represent a true upgrade in optical quality and coverage of an exit pupil that you don't have covered. There are objects that you will only get with large exit pupils. That's the point. It's not just about fov.

    Much less pricey is
    https://agenaastro.com/gso-50mm-superview-eyepiece.html

    It's also not as good as the Tak. But it at least covers the large exit pupil domain but without the contrast of the Tak. I can get the same objects with it as the Tak for the most part but the contrast is not quite as good.

    If your eyes are young and can dilate to 7mm then Gary Russel makes some nice long fl eyepieces.

    Russell Optics & Machine

    Now as to the problem of swapping eyepieces about..... that's easy to cure without replacing your set. There are two methods:

    1) carefully select only 3-5 for a given evening, since that is all you really need or
    2) get a zoom like

    https://agenaastro.com/baader-hyperi...w-2454827.html

    Use the zoom to dial in the optimal focal length and then settle on the fixed focal length eyepiece you want to use. This particular zoom is optically very nice but the fixed focal length will do better.

    I have compared Hyperions with ES82 and ES68 in my 8" SCT. Both Hyperions and ES EPs performed well, but ES EP definitely have edge at higher powers (above 100x). ES EPs have sharper focus and less light scatter on bright targets. As far as transmittance for dim DSO targets they are about the same.

    I don't think larger FOV itself justifies the upgrade, for me ~70 deg is already large enough. Besides, ES82s have shorter eye relief and due to their design (recessed top lens) I can't see whole FOV anyway.

    Still at shorter FL I feel there is enough benefit to try ES. I suggest to try ES82 11mm first. I consider it one of the best in the line and it matches well 8" SCT. If you like it you may consider adding more.

    At lower powers (31-36mm) I actually prefer Baader Aspheric because of great performance in 8" SCT and much lighter weight and smaller size compared to ES EPs.

    Consider that the max true field of view of the C8 is about 1.6° because of the baffle tube. Your 31mm and 34mm yield TFOV larger than that so upgrading those focal lengths gain you nothing.
    However the 18MM and 14MM would gain useable FOV.
