DO BAADER HYERIONS COME CLOSE TO PENTAX XW

but unfortunately they are in a different league in terms of price and performance.

i would have like a little more elaboration.but i guess reviews could be somewhat bias.
In general terms, swapping telescopes make the big, hit you in face, can't miss differences, swapping eyepieces make subtle differences.
People argue about whether the Nagler T-6 or Delos is better than the Pentaxes, (depends on your scope) but they Hyerions are not quite at that level.

Eye relief and the annoying large FOV that some report non withstanding. YMMV.

Viewing aesthetics, most of the Hyperions I think do not have a sharp field stop. I have the 17 and 10mm and used to have the 8mm and only the 17mm has a sharp field stop, while the others had blurry ones, which detracts from the view and makes the FOV seem a little smaller to me than the 68* that it really is.
Light-throughput wise, XW's are among the highest rated. The XW's are known for crisp, sharp views and while the Hyperions can deliver decently, some observers with more experience than myself have characterized the views as a little 'soft'. Soft or not, while doing some casual A/B/C testing with three different 10mm eyepieces not long ago (XW/Hyperion/Delos), I could see the same detail in Messier objects in the Hyperion that I saw in the XW and Delos. I was careful to choose faint detail and stars in the objects in order to have a basis for my comparison but perhaps some more thorough testing or critical observers would be able to ferret out the differences.
As far as edge correction is concerned, the Hyperions are not so close to the XW's from what I have read. My primary scopes are not 'slow', so I cannot speak from experience on this.
In terms of size and weight, they are close as well. Price-wise, big difference, of course.

Plus, the ES 82 degree is better than Hyperions.

im hearing there great eyepieces,im mostly into the planets.thx
IMO they are not close. Hyperions are good eyepieces and I had most of them for quite a long time in the stall and enjoyed them very much. Very comfortable to use and nice sized eye lens and wide AFOV, plus the fine tuning rings were a blast to use. But the XWs have a much better off-axis in faster scopes, on-axis they are crisper with a higher apparent contrast to the image, they are also very neutral toned so colors are more vibrant. Overall a much more refined view than the Hyperion...and of course you pay for it. And in the 10mm and shorter focal lengths the XWs are essentially as good as it gets over their entire FOV. FWIW, the XWs are the only wide fields I have used that I find much more than simply acceptable for planetary observing (I'm very picky about planetary)...they are really quite capable in that specialized observing role!

The Pentax is more comfortable to use, doesnt incline to bean or blackout, is sharp to the edge, has fantastic contrast.
In fairness the XW is three times the price so you'd expect it to be a lot better and it is.

In my opinion, with the prices of the ES82 line, the Hyperion is basically redundant.
I agree. The ES82s are amazingly good, unbelievably so for the price. They have made a LOT of eyepiece lines redundant, IMO.

Compared to cameras, Hyperions are Kodak, Pentax are, well, Pentax.......
that sums it up nicely.
in a f/10 sct. i found that the hyperion ( or stratus) was very close to naglers or even an ethos. many use the hyperions with success in sct. once your scope becomes faster or once you want to get the best view wth very small detail, suddenly the price increases significantly.. that is life,
for a designated planetary EP i would prefer a UO ortho to the hyperion. but that is very personnal
i agree with others that the ES eps are a good value for the price
