Looking at the 100 and 110 degree samples from each they look the same except the Lunt does not have the polished barrels. Are the designs of these two similar?

The Tele Vue Ethos 100 and in particular the Ethos 110 SX are based on Al Nagler's Simulator eXperience and his work on the lunar module simulator for NASA over 40 years ago.  Anything else on the market is an attempted clone.

I've used eyepieces both lines.  The Lunt is excellent but the Ethos is better.

I felt the Lunt Xwa to be the most ethos-like among the clones, as regard presentation.  When comparing 20 ES, 20 Lunt and 21 ethos,  20 Lunt showed slight astigmatism at the  edge, . 20 ES showed more, and 21 Ethos showed none in a GSO-coma-corrected /12" F5 reflector.

That was my assessment too.  I really felt the 9mm Lunt is more like the 8mm Ethos than the 9mm ES100.

I agree. The Lunt 100/110 eyepieces are a remarkable value.  I don't understand why more people

haven't picked up on this. I saw them displayed for sale at NEAF this year and no one was looking

at them. Everyone who has looked though one loves it. For some reason, probably availaility, the

buzz never got out on these. Not many vendors carry them but you can find them if you look.

I own a Lunt HDC 20mm and to me it is a great eyepiece. 

In my F6 dobson without coma corrector, I do not see any astigmatism across the field and at the edge, but I do see a modest presence of coma in the last 5-10% of the field. To describe this, stars at the edge appear like very little comets with the tail pointing the field stop. No star in any part of the field of view appeared like a seagull or cross when on-, in-, or out-focus. 

 

It is a lovely eyepiece, very light for its class, and comfortable to use. For its cost, it is a total bargain.

I have the 9mm and I think it's a phenomenal eyepiece. I've never looked through an Ethos, and I'm not very tempted to.

Almost all my main ep kit is Ethos/Delos/Nagler but if I was smart enough and was just starting to build a kit I'm pretty sure the core of it would be a complete set of the Lunt XWA's or the ones from APM. I think they're the highest value ep's at the top end of performance.

The Ethos are likely a bit better but the cost difference is wider than the performance gap.

I too am surprised they are not getting more buzz.

 

Edit - I just looked and the APM website has packaged the 20, 9 and 5mm @ 553.78 Euros net export price + freight. Such a deal. And the ergonomics are better than TV.

I understand that the 13mm XWA is soon to be released in the upcoming months.  Price is the same as the 9mm - $210.  I am waiting eagerly.

Are Lunt only available through APM in Germany?  Where do I find the specs for these EPs?

 

Edit: Found the specs at APM Telescopes.

Too late for me. I already have a 13 Ethos. If I didn't though, I'd be all over that same as you!

Eagerly waiting for the soon to be released Lunt 13mm 100°.

At long last a Lunt 100° eyepiece to fit the gap between the 20mm and the 9mm.

 

I compared the Lunt 20mm 100° to the ES 20mm 100° - kept the Lunt !

I compared the Lunt 9mm 100° to the ES 9mm 100° - kept the Lunt !

I compared the Lunt 5mm 100° (actually 4.7mm) to the ES 5.5mm 100° - kept the Lunt !

 

I see a trend - the Lunt 13mm 100° should be pushing the ES 14mm 100° out the door !!

I was looking at the Lunt and WO 5mm 110 offers and given the choice I would rather NOT have a rotate up and down eyeguard. Looking at the Lunt at the Farpoint site, does this eyeguard roll/fold down or is it to stiff for that? Thanks

Mike

I just leave my 5 Lunt eyeguard in the down position so I just checked before answering your question.

It is a rather stiff rubber eyeguard but it rolls up and down just fine. In the down position I find it very 

comfortable with plenty of eye relief with my glasses off. The eyelens has stayed very clean.

What brand are the XWA's, can't read the name in this pic?

 

Wow, a 3.5 mm EP! What do you use that in? I could never use a high power EP in any of my scopes. The 5mm is the highest and only used on perfect seeing nights.

Only for high power in the low focal length scopes, the two apos, 80mm(142x) and 115mm(230x), and in the small newtonian 130mm (213x).

I have just noticed that EyepiecesEtc.com has a placeholder for a Lunt 12.5mm 100°: click me.

 

Let's hope this is happening... waytogo.gif

I see a trend - the Lunt 13mm 100° should be pushing the ES 14mm 100° out the door !!

When ES came out with the 5.5mm I was hoping it would be 110 AFOV (Not 100 AFOV which it is).

Now I see both Lunt and TS have a 5.0mm with 110 AFOV.

 

Perhaps ES selected 5.5mm because 5,0 would have been too close to 4.7 and it was far enough away from 6.0.

Could ES have made a 5.5mm 110 AFOV? (They make a 9.0mm 120 AFOV).

9mm 120 AFOV, 25mm 100 AFPV, and 30mm 100 AFOV 3" are all not clones - those were innovations!

Yeah, they would indeed appear to be just that!

Well, taking that at face value... it would be either an attempted replica, or a clone. An "attempted clone" is an odd term... would, i s'pose, be reserved for when someone clones the clone? scratchhead2.gif

 

The Ethoi i've acquired were done so thru *used* channels and at excellent price-points; to entertain one of these Lunts (which my frugal soul yearns to do! shakecane.gif) would have to factor for a used-versus-new accounting... prob'ly not worth the FU$$. But given the chance to do it all again from scratch, based on what i've seen with the Lunt 20-100°.... i'd stock up on the Lunts!
