    You should check out the EPs Harry Siebert makes in his backyard shop in rural North Carolina. Very good value for the money. No pin cushion effect.

    I went to stellafane and here is what I can offer you for my impressions on eyepieces:

    22mm nagler - Great FOV, wonky design. 7/10.
    24mm panoptic - looked at with a binoviewer, but was able to close one eye and see through just one. Smaller FOV, but very clear and crisp stars. 6/10
    41mm panoptic - Ridiculous. Resembles a grain silo, only bigger. 7/10
    31mm nagler - Much better all-around EP than the panoptic. Takes in a massive chunk of sky, with every star a perfect "diamond on velvet" point. 9/10
    21mm ethos - Only got to look at M13 through this, and I could care less about globs. Still, it was plugged into a 32" dob, so the view was still pretty good. Overhyped. 8/10
    17mm nagler - This was plugged into a $12,000 Astro-Physics refractor. Nice views, but the "expansive space-walk" feel just wasn't there. 6/10

    I gave you a couple more reviews than was needed, in case you were looking at other eyepieces. I think the 35 panoptic would be a joke on your telescope - it would knock the poor thing over. The 17mm nagler would be a good mid-range, but it's a bit.... lame.
    It would help if you could get to a star party. But if you can't, here's my prediction:

    I looked through the 41 panoptic and 31 nagler. Average them out and you get a 35 panoptic. I would suggest the 35 pan over the 17 nag. Why? Put a UHC filter on the 35 panoptic and take in the expanses of the veil. You should be able to take in most of the veil with no trouble with this bad boy in. Fin.

    thanks for the info m8. there way more to consider than what i had initially though about and as i get more info, actually looking through each eye peice seems to be the only reasonable solution to base a decision on.

    one good thing is that the scope i have has these teflon break pads and i can tighten a nob to press down on the breaks so to speak. so i'm thinking the added weight of the larger shouldnt be a problem. but again, i;d rather not spend 300-400 bucks and then realize that my break pads are not good enough hehe

    You might think about Meade Series 5000 Super Wide Angle if you can find one. They have the same FOV as the Panoptics at 1/3 the cost. Since Meade is no longer producing the SWAs they are half price at about every supply place. I recently purchased one for $85 US new.

    I love my panoptic 35 owned it for long time now, this is the one EP which really gets some mileage!

    The 17mm nagler is very nice but believe there are better EP'S out their for much better price! I have used two 17mm Naglers in binoviewer with very large apperature DOB, now that was a real treat!!

    My 20mm nagler sees more use than 17mm. Lots of choices but best one can do is to test them in one's scope first, if at all possible. Everyone's eyes are different and every brain processes the views a bit different what is comfortable for one person my be awful for another, likewise views are completely different scope to scope.

    I bought a Panoptic 35mm a month ago at Golden State Star Party and haven't noticed the pincushion effect while panning across a star field, either with my 4" refractor or with my 12" dob. The EP has had plenty of use already both at GSSP last month and at Oregon Star Party last week.

    I'll have to look for the pincushion effect and see if I notice it. If it were very prominent, I think I would have seen it by now.

    I've never suffered from motion sickness or sea sickness. The only problem for me is the sensation of vertigo when standing on a ledge of a tall building and spiders lol. I'm very curious to find out for myself how big this pincushion effect is.

    So, did you hook up with the FVAS on your trip to God's Country? How was the airshow? Hot, I'll bet.

    I may be going to Miramar in October.

    Panoptics are without question, really great eyepieces; my 27mm is my favorite among the longer focal length 2" EP's. If there is much light pollution where the EP is used, the 27mm is preferable to the 35mm as the former can give a nicer dark background with its more magnified view.

    Here's a passage about pincushioning (which does not bother me) in a review of the Panoptic line (15,19,22,27,35mm's):

    Pin Cushion Distortion:

    The only problem with Panoptic eyepieces is something called "pin-cushion"

    distortion. If you have a Dob, for instance, and love to pan around the sky, the starfield is magnified

    slightly more towards the edges. In fact, in looking at a ruler, even while stationary through the

    eyepiece, the ruler looks bent.. it's sharp, but the trade-off is a distortion that bends straight lines.

    When panning, this can literally get you sea-sick. The distortion is very minor to some folks, and

    bothers other's more. Most people have not noticed it that I have spoken to..but those that Pan

    around a lot certainly do, and it is very noticeable in daylight. The distortion is correcting the

    performance near the edge of field though, which is the goal. ..
    ..If you had to choose only one, I would pick the 27mm Panoptic. ..

    @Pierre: The airshow as absolutely fantastic. It was my first. Weekend of many firsts, dark sky, air show, road trip, sleeping in a tent lol. They had a whole tonne of birds on the ground. One of only two operational Lancasters in the world! having flown that enough times in WW2 sims, it was a real treat to actually be inside one. Had a few conversations with some of the USAF air crew about how they operate and such. The air fueling tanker's crew i thought was the best, good sense of humor and very open on explaining how the airplane worked and how its used in the field. The Thunderbirds and the Snowbirds were an absolute treat to watch. They kept playing topgun music on the speakers and it was totally awesome!
    We didnt end up going the the meet at McDonald park on sat. Given our experience earlier with the dark skies, we decided to take in as much of that as we could instead figuring, we'd have another chance in sept in alberta. We could have learned a lot more i suppose but we got an adapter that allowed us to run my notebook computer with stellarium hooked up to the car. Timing worked out in our favor i guess, a week late and all we'd have was smoke!

    @Hernando: Thanks for the link and the info there m8. THe more i am reading about it, the less i think the pin cushion is going to bother me. I do a little bit of panning around while looking into my dob but not much. I use my finderscope to do that most of the time. Its definately sounding good. That said, hpgeek did bring up the Meade SWA, now i didnt seriously consider it before but at a hundred bucks less, the cheap guy in me is taking interest lol
