Very cool! I can't wait to hear your impressions of it once you get it out under the night skies.

+1 Look forward to the reports. Don't know if I'll jump on the sale price or not. I've been fortunate to have accumulated over time an almost complete set of Ethos, but I'm wondering if the new ES 25mm could replace both a 21E and the 31T5 I've been hanging on to. The 25mm might be a better jump to my 17E than either one and it would also lighten up my EP case a bit.

Don't forget those special unobtainium lenses.

Seriously, companies advertise products before they're available all the time,
but usually it's only a few months. There could have been some glitches that made them postpone production.

Like, perhaps, having so much demand for their eyepieces world-wide that there is a shortage? if working on a 5.5x100 means you can't make more 6.7x82 and you're back-ordered up the wazoo on the 6.7's, it might be prudent to postpone the 5.5, eh?

I'm sure that their pricing on their current eyepiece offerings has resulted in a sale volume that is slowing things down on some of their in development eyepieces. But they already have a prototype for a 3" 30mm 100 deg eyepiece and none for the 5.5mm 100 deg that has been listed as pre-order for over a year. That doesn't make any sense. And their 100 deg line needs something in the 5.5mm range so you would think there would be a bit more urgency about that.

Manufacturing and development are ususally done by different people.

I like ES sharing future product intentions, but whish they would also advise expected timeimg: < 3 months, < 6 months, < 1 year, < 2 years, or > 2 years.

Had I known the 5.5mm 100AFOV would still be a year away, I may have gotten the 4.5mm 110AFOV for XMAS whilt the TV sale was on. Don't mislead customers, unless you are early.

As a confirmed eyepiece addict, "lighten up" has not become part of my vocabulary yet (although I don't always take all my eypieces out, depends on how long I plan to observe, and what my goal for observing that night is).

Got the last 25mm 100 Highpoint had. Could not believe it was still In-stock this morning! No waiting list there I guess?
Now when is the 9mmm 120 going be in stock at Astronomic or Highpoint i wonder?
I'll send a pic and report once I try it out the 25mm 100.

Your comments on eye relief would be very much appreciated. I can find no mention of ER in the specs. Thanks.

At Astronomics is referred as 14mm. This model seems to have better top ep and rubber eyecup designs than the others ES 100 models (on those there is 2 or 3 mm ER loss for eye-glass users...), so hopefully 14mm is the usable ER for eyeglass users...

Hi Jeff,

When you have a chance, could you measure how much inward/outward focus distance ES25-100 is required to come to focus to infinity comparing to Nagler 31T5?

I am hoping that ES25-100 doesn't require more inward focus than Nagler 31T5.

Thanks.

Tammy

+2 I've got complete set of Ethos and a 31T5 myself, and I'm very happy with them all, but I'm similarly thinking about replacing the 8 and 10mm Ethos with a 9mm 120 degree ES, and my 21E and 31T5 with a 25mm 100 ES. Sure, it would be nice to have them all, but economic considerations aside, I sure don't *need* them all and besides, these bad boys would take up lots of real estate in my EP cases!

I have a large Pelican case but I am considering selling my Nagler T4 eyepieces. I no longer have room for them in my case. I should sell all 3 to finance and make room for a Paracorr Type II.

My 12T4 is the furthest from being par focal with the rest of my 2 inch eyepieces.

Hi Ken, It's funny that even though I would confess to being an eyepiece addict I now have fewer eyepiece than I had five years ago and still trying to thin the herd even more. As I said, sometimes I use only two eyepiece in a whole session with my dob in darker skies and don't think I'm missing anything. That is, unless the seeing is better than average and then 1.6x and 2x barlows could solve that problem.

Agena Astro's web site says they have this eyepiece in stock but "photo to follow".

Here is a link to a picture. 25mm EP Pretty much guarantee they will all look just like this.

The 14mm is the usable eye relief that we measured from top of the rolled-down eyecup to the plane where the image forms. ES has yet to specify the eye relief on their website, but it will probably be in that ball park. The image on our website was one we took after measuring the eye relief.

Well, since Astronomics was out of stock on this eyepiece I went to AgenaAstro and added it to the cart. While I was there I added the ES100 9mm and the Paracorr 2. I then clicked checkout and that came to $1370 before shipping. I then decided I would rather not get divorced just yet so I closed the tab... Oh well...
