Given what Ethos is purported to do, I think it could be a very long time before something better comes along.


One possibility is that TeleVue might take the Ethos design and adapt it to an 82 degree field, creating a Nagler Type 7. Giving up the extra AFOV might yield more eye relief. That might be of interest to those who say they don't want or need a 100 degree AFOV but like other aspects of the design. TeleVue did something similar when they used technology developed for the Radian to create the Nagler Type 4.

In the UK I reckon about £6789.76. We always get ripped off.

In 1999 Al Nagler had shown a 100 deg FOV eyepiece to Ed Ting. This is what Ting had posted on his (excellent) website scoperewies.com:

(Quote) There is no "magic" to building a super-wide FOV eyepiece. Al Nagler once showed me how to make your own 100 degree FOV unit: unscrew the barlow from the bottom of a Radian. (End quote)

THAT SIMPLE?

Of course, not. Why do you think it took Nagler almost a decade to come up with a working prototype? As Ed Ting continues:

"The challenge is making a wide FOV eyepiece that's sharp to the edge."

Hence the wider air spaces and possible asphericity (doubt that, I have my money on the "unbarlowed" Radian design with minor changes. This will explain the light weight, too!).

In any case, a MUST have.

$199. Please please please please please please please $199.


That will probably make an acceptable down payment. :shocked:


Actually, the "down payment" (at OPTcorp) is $1
The "deposit" when pricing is announced is 10%

I'm "on the list" sigh

There goes my savings account!


...and then some! The 13mm is only the first of a new series of how many? four, five, Ethos eyepieces?


Errr....we don't know!!

We don't know if there will be other focal lengths offered, and if so, what they'll be.

We don't know what the price of the initial Ethos will be.

We don't know the optical design of the Ethos.

Jim


Jim,

I've seen this eyepiece and looked thru it. I don't care what the design is. I want one!!

The Company 7 website sez that there will be a series of Ethos eyepieces and even lists the focal lengths. Also, Televue has a long history of going into production with new products soon after the announcement.

As for all the speculation on price: All I know is what I heard at NEAF when a Televue rep told the Meade rep that the price would be "no where near that amount" (he had suggested that $1,000 would be his limit for a personal purchase.) I think it says something when the main rep of one of your big competitors (Meade) says that he plans on buying your product for personal use.

...or to use in designing a Meade knock-off. :shocked:

Ther IS historical precedent for this...

I doubt that the Ethos will be as easy to improve upon as the T1 Nagler was.

This product release and thread will likely be cited in future marketing curricula as a textbook example of what the "market will bear" business model.

From an optical perspective, when I read "light weight" and "whiter color" and "flatness across the field" and other "without comparison" superlatives, I immediately think plastic internal apsherics with glass outers. This is just the kind of "out of the box" thinking I (we?) should expect from a pioneer, dare I say "guide star" of the industry.

So, the marketing conundrum facing Mr. Nagler is how much to charge for an eyepiece that is likely cheaper to produce and outperforms his existing line? As much as he can, before the genie is out of the bottle and somebody else follows suit. In the meantime, judging by the "bids" as represented by this thread, the price will be $600 (average bid) with a first standard deviation of $160.00. In other words between $440 and $760 by this thread's account, would capture this market and likely not hurt his existing product line.

I don't care whether the Ethos has 20 elements or what the lenses are made of. With performance that incredible (and it is!) it makes no difference to me. BTW, I guessed between $400 and $500. :cool:

I would guess that they would price it slightly higher than the 31 in price... citing today's higher R&D costs. :)

I dunno; so far all TV eyepieces have increased in price over their intro prices.

News from TeleVue today--it's $620 retail.
Now, who won the poll?

Yep - I just got my "do you want to buy it at this price" confirmation email...

I said "yes" - based on my pre-order date, I should be (hoping!) in the first tranche of shipments at the end of this month... the second tranche is supposedly end of October...

We shall see how long I hold onto my 12T4...

I am going for it too. Im forgoing buying a 12mmt4 and am selling my 17mmt4 as it has virtually the same fov and should have much higher contrast. But did I do the RIGHT THING!!!!

I need that whole brightness/contrast thing explained to me again. I need to find the thread, review, or report which educated me on the topic. Does the contrast at higher power trump the brightness at a large exit pupil?

And now for a completely different topic,,,
Quoting Larry Geary:
"One possibility is that TeleVue might take the Ethos design and adapt it to an 82 degree field, creating a Nagler Type 7. Giving up the extra AFOV might yield more eye relief. That might be of interest to those who say they don't want or need a 100 degree AFOV but like other aspects of the design.

Now that would be cool for us glasses wearers! :watching:

I've had my Ethos for about 2 months now. The CN review pushed me over the edge and I had to have it.

It's the only EP that has actually made me motion sick (just a tad, folks!) while I was slewing while looking through it. Now THAT'S a wide FOV!!!
