    Default First light: Baader Hyperion 8mm, 17mm and GSO Superview 30mm



    I have hazy sky and high drifting clouds tonight but it's the first night since I got my new eyepieces that I can actually somewhat see the sky. I wanted to write a better review than this but I was trampling around in mud, was cold and my feet hurt from a long day.

    I'm using an Orion Xt8, (5.9 focal ratio) previously only with the included 25mm plossl.


    --------------------------
    GSO superview 30mm:

    With the 1.25" adapter removed to fit this 2" EP the focuser can't focus far enough. I have to loosen the screws and pull the EP out a bit then re-tighten. Nice clear view.

    First thing, I love the eye relief. It just feels natural. No squinting of any kind. There is a noticable distortion around the outer edge with my 5.9 focal ratio. When looking at something like the Orion Nebula I'm not bothered.(it looks quite amazing in this ep actually) But when looking at Pleiades, seeing the outer stars out of focus is a bit irritating.

    Compared to the included 25mm plossl this is much better(most because of eye relief and field of view. The plossl gave the sky bit of a greenish/blue color which I kind of like though. The GSO seems more natural in color. Very neutral.

    The sky really pops out with this. Seeing many many many more stars that I wasn't seeing in the plossl.

    Overall, This makes Pleiades look amazing and it's revealing stars that I can't see with anything else. The distortion around the outer 30% or so of the field of view is quite irritating.

    This will be the EP I use when just looking around the sky with no goal. If I find something I'm switching to a different EP though!
    I like it, slightly dissapointed but is a huge improvement over the 25mm plossl. If getting one eye piece, I wouldn't go with this one alone. Probably more enjoyable with slower scopes.
    -----------------------------------------------------

    Baader Hyperion 17mm:
    This is nice. Sharp all the way across the field of view. Very natural looking color. I wish the GSO had the clarity of this ep. Good eye relief. Nice crisp view of Jupiter. I didn't play around with this much as I was anxious to put in the 8mm and have a closer look at a jupiter. But before I did, I unscrewed the 1.25" lense group and used it as a 2" EP making it 21mm. It looks awful this way. Worse than the 25mm plossl. I would not recommend buying this for the purpose of using it as a 2" EP!

    Overall, this is most likely going to become my DSO eyepiece. I like it a lot. Kind of wish I would have skipped the GSO and got a 25mm Hyperion. Just didn't want to fork out the cash.

    -----------------------------------------------
    Baader Hyperion 8mm:

    Wow. I have hazy sky's tonight but this still gave me a good look at Jupiter. Clear to the edge. Feels identical to the 17mm.
    I then unscrewed the outer lens group and tried the adapter rings to give it more focal length. With both rings on, Jupiter nearly filled the EP. Bad seeing tonight though so I removed one of the adapter rings to back it off a bit. Much better. I'm glad I went with the 8mm instead of the 5mm as the 5mm would be limiting in use such as nights like tonight. I nearly dropped the adapter rings and out lens group in the mud while doing this in the dark. I almost learned to not do this the hard way! I really like these Hyperions and reccomend them. I'm a newb though so I don't know if that means much.
    ----------------------------------

    I guess that sums it up. Wish I had a better sky and without aching feet. Overall I'm satisifed. Slightly dissapointed with the GSO though. Should have spent the extra cash on another Hyperion. I'm sure I'll be using it none-the-less. Probably the first EP I'll be putting in the scope every night to have a look around. I might have better experience with a better sky as well.

    Thanks to everybody for answering questions while I was trying to choose what to buy!

    Hi there, great review and comparison!

    I am happy to hear you got the Baader Hyperions but surprised you didn't get the zoom, can you post your reasons why for your XT8?

    Also very interesting to hear the GSO eyepiece cannot compare to the Hyperions.

    Did you try any barlowed?

    As I am getting into visual more, and have a discount off the Hyperion line I was thinking of getting a few and would more likely get a low mm eyepiece for lunar & planetary viewing as my GSO and Orion plossls don't do my optics justice or the zoom that is why I am very curious for my first question above.

    The 24mm Hyperion is not as highly rated as the others in the series, it is a slightly different optical design.

    I can vouch for your experience with the 17mm - got mine a week ago and had about an hour at the eyepiece - Even that brief experience convinced me this eyepiece will be my go to of the future

    Yeah, it seems logical to get the zoom with the dob. I just felt like I would be trading off visual quality for convenience if I got the zoom. Visual quality is probably the entire point of this hobby in my opinion so that made it an easy decision for me. Convenience is great, but if you cant see what you want to see then what's the point?

    I don't own a barlow so I can't comment on that. I figure the fine tuning rings that I purchased with the ep's make up for it. With the rings, each of the hyperions can be 5 different focal lengths. (although like I mentioned, using them as a 2" ep is awful)

    With the 8mm, and my 1200mm focal length I'm getting 150x zoom. A nice amount on Jupiter. I was craving more though which is why I put the rings on. With both rings, giving me a 4.3mm, gave me 279x. I had hazy skies, but I feel like this is a perfect spot with a clear sky. I pulled one ring off and that helped a lot. I don't know which one though as I was doing this in the dark! Keep in mind, I was looking at Jupiter through a thin layer of cloud/haze. I imagine this will be perfect with both rings on a clear sky.

    I could see very very sharp detail considering the conditions. Looked like a good photograph. The 2 thick bands and all of the color-y swirls which I couldn't see before with the plossl. (only the 2 bands which were hazy at best)

    Some additions to my review:

    The GSO does look VERY sharp in the center. I am quite pleased with it. Seeing the mess in the outer field jumping around is ugly though. The center of the field (which is quite a bit more fov than the plossl anyways) is way sharper than the plossl.

    With the adapter rings on the Hyperions I was getting a focused reflection in the eyepiece that was moving around as I moved my eye around.(looking at jupiter) Without the adapter rings this goes away. Not annoying at all though.

    You got yourself some good eps there. Sounds like you need to get an observing chair soon to help take the pressure off your aching feet.

    True Dat! Anyway, when I owned my Hyperions, I actually enjoyed the 24, 17 and 13 the most. Also, I preferred the views thru the single EP's rather than the Zoom in my dob. They just worked a whole lot better.

    I've read alot of different experiences concerning the GSO super EP's.
    Most of which were quite favourable.
    I have also read a lot about the Baaders and they do seem to outclass
    the GSO's in optics...but not price.

    I guess you could say..if you have the cash go for the baaders,
    but...
    the GSO's are good pieces in itself..
    If you don't mind a pure focus and square away 40% of the FOV then
    I think the GSO's are good price/quality value
