I'm asking. Looking for good eye relief and fairly wide AFOV. Preferably with a large eye lens. Any suggestions?

They are $120 retail, but I think the Baader Hyperions are worth the extra $20...

I agree. What you're describing in a desired eyepiece is what a Baader Hyperion represents. All except the 24mm have 20mm of eye relief, eye placement is quite forgiving, 68-deg AFOV and edge correction that'll hold up well until you get down below f/5.
Clear Skies,

You didn't say what focal length you are interested in.
High-power the Burgess Optical planetaries are very nice. 20mm eye-relief, adjustable eye-cup, 60 AFOV, very comfortable to use.
At low-power the Knight Owl 30mm 80deg is a steal at around $80. (Similar EP available under different brand names). You will have to pay 3x the price for a step up.

ill second that opinion....
Get some baader hyperion 68 degree modular eyepieces. 119 dollars, but they're really worth like 200-300 compared to what they perform against.

My list of good EPs for $120 (that extra $20 really is necessary) or less which I own and use:
8-24mm Baader Hyperions (24mm is the runt but still decent in f/6 and above). I have no reason to believe that the 3.5 and 5mm are any different.
2.5, 3.2, 6, 9mm BO/TMB planetaries. Again, I have no reason to believe that the others in the series are any different.
40mm WO SWAN (best above f/6). Based on reviews here at CN, the 33mm is as good, some others in the series are not as good.
30mm 1rpd and it's many clones (best above f/6). No others in this series.
9 and 6mm Expanse and it's many clones. The 15 and 20mm of the series are not as well-corrected. The 9mm is very much like the BO/TMB 9mm but with 10° wider FOV and no convenient twist-up eyeguard. 6mm reported by some not to be quite as sharp as the 9mm (though I don't see the difference) but still very good.
Hon. mention: 20mm GSO Superview (best above f/6)
Commonalities between these EPs:
All have excellent eye relief and I can use all with my glasses on
All have at least 60° FOV:
BO/TMBs - 60°
GSO SV - 65°
Expanse - 66° (really ~70° for the 9mm)
Hyperions - 68°
SWANs - 70-72°
1rpd - 80°
other <$120 EPs I don't own but which I know are good to keep an eye out for:
used 10mm or lower Speers-WALERs. I have the 1st gen. 5-8mm Zoom and other reports for these shorter FL Speers confirm their *excellent* edge correction, especially for an 80° EP in fast scopes. IMO, these are the best "inexpensive" EPs I never tried out.

It would appear that all of the baader hyperion eyepieces are of the same modular construction EXCEPT for the 24mm as a different setup was required for this focal length.
The 3.5 and 5mm and the same exact construction as the all the others.
Notice on the table of possible modifications using the 2 different Fine tuning rings, ALL of the eyepiece focal lengths are listed except the 24mm.

 Yes, I like the 5 element 2" SuperWide ~70° AFoV designs, (mine is a 32mm Burgess). Hyperions are quite happy above f/7, perhaps a used one can be had - if you can wrest it loose.

How much eye relief is "good"? Do you wear glasses? Is there going to be a specific telescope that will be the main recipient of the particular eyepiece? Are you after a 1.25 or 2 inch diameter eyepiece?
Sometimes matching the telescope to the selection creates more leeway. A long focal ratio telescope is a lot more forgiving when it comes to using cheap widefields.
There is no way for anyone to prove whatever selection is "best".

This is one spot where listing one's equipment would be helpful. Best at f/4 is a lot different than at f/10...

I don't list my equipment. I believe it helps a lot to ask a better question,that way we don't have to be mind readers.

Baader Hyperions for higher power.
Agena Astro 2" for lower power.

Sorry, but it's TeleVue Plossl's and Orion Ultrascopics that represent the best optics available for (on average) about $100 per without going over. 50-52 degrees is a fairly wide field of view. Plus, I still stand by Don Pensak's famous truism:
optical quality, wide-field, affordable (choose any two)
I'll admit that in the 68 degree AFOV range the Hyperion at $120 (formerly $99) stands tall, but is the power of a 68 degree AFOV field sufficient inducement to sacrifice any level of optical quality?
If the best in class is desired for 68 degree AFOV, then the Panoptic would be my choice, followed by Pentax XW in the shorter FL's which are not available in the Panoptic line.

To All,
Thanks for trying to answer my vague question. Should've known better to not list my equipment. Right now, I'm very diverse in that my main scope is an 8" SCT (f10) and my second scope is an ST80 achro (f5). Perhaps no eyepiece is going to be perfect for both simultaneously. And yes, I do wear glasses when I observe. I'm just beginning to really study eyepieces in depth, so really all of your replies have taught me a lot already even if the info doesn't necessarily apply to my equipment and situation.
Right now I have a very meager selection of eyepieces: 40mm Sirius plossl, 25mm Celestron SMA Wide, and a 7.5mm Sirius plossl. I also have an ancient set of Criterion eyepieces: 18mm, 12.7mm, and 7mm. While the Sirius plossls perform ok, the peephole in the 7.5 is bothersome. The Celestron isn't bad and easy to look into, but does have a good deal of curvature around the edge. The Criterions actually work pretty good in the SCT, but have a very narrow AFOV and, of course, small eye lenses. I need to fill in the gaps on focal lengths (not considering the Criterions) and would like to retain as much eye relief and AFOV as is practical without sacrificing optical quality (especially when it comes to curvature around the edge). I can't afford an Ethos and many high-priced Televues and the like.
Now, by golly, if I had only said all that at the beginning, this thread would be a bit more coherent perhaps. Sorry. Still learning here.

No doubts:
University Optics Orthoscopics - two families, $60 and $80 each. There is no sharper eyepiece for planets and the Moon, and they are utterly distortion and color free. My favorite ever eyepieces because they "just do it", lack any sort of holy relic effect, and are a perfcct fit of form and function.
Meade Series 4000 Plossls - $299 for a set of six with case, $199 if purchased with any scope at all - $50 each up to 26mm, $70 for the 32mm and 40mm, $100 for the 2" 56mm Plossl. The latter is an impressive eyepiece in its brutal simplicity and utter solidity. They make great choices for binoviewers because of their low price. solid build, great eye relief, light weight, and excellent optical quality.
For some reason it is fashionable to look down on Meade accessories. Don't be fooled. These are the best buy around in eyepieces, along with their spiritual brothers from Japan, the UO Orthos.

The Ultrascopics, Orthos and Plossls suggested here, while all very good to excellent EPs, all also have peephole eye lenses below 15mm or so. This leaves the Hyperions and other similar long eye relief EPs as better options for avoiding the short focal length peepholes.

Yes, this is everyone's choice. So far, I've made the inexpensive widefield compromise and enjoy my views though now that I have an f/5 scope, I only use my BO/TMBs, Hyps, and WO UWANs (which I got for $130/ea on sale).
