I just received my new 11mm on Thursday. The box is the new style. On the label on the box says N2, but the label on the eyepiece itself says Ar. Just like frito says.

I bought my from OPT, so maybe thats why my 11mm is still the N2 purged style. I dont mind either way as far as that goes really though.

if they shipped it from their own stock thats probably why. i bought my 11mm from telescopes.com (hayneedle) and hayneedle had it shipped from ES in AR direct to me.

Ordered from Astronomics on ES82* 4.7-6.7 and 11mm ,all back order . Why Astronomics not call and have ES factory shipping to customers ?

I would much rather they come from Astronomics, rather than the ES factory. If you have a problem with one, would you rather ship it back to the factory and wait, or have Astronomics handle it for you? :grin:

Funny, I bought my Explore Scientific 11mm 82º last month in Madrid, the eyepiece itself reads Nitrogen-Purged in the top part but has the Argon (AR) green sticky.

Who can guess what's inside this particular eyepiece? :grin:

Of course, having insulative properties between groups in an eyepiece might actually be a bad thing...It would be disastrous in an objective group. :thinking:

Since rubber seals seem to last longer with Argon inside, I believe they are in the process of converting all N2 purged eyepieces to Argon.
At least, that's what I heard.


I finally heard back from Explore Scientific on this issue. When I received my 'Nitrogen' box (box indicated nitrogen purged ES82 series), with an Argon lettered (says Argon purged) with Argon symbol on sticker (Ar), I inquired from ES what was up with that. In part, because I had some initial concern about a possible knock-off/copy, but also because it was (to me, as a consumer) confusing with no insert to explain the reason for mismatch box to eyepiece, or an ongoing conversion taking place and nothing on their website to announce a change was in process.

So, here is the official response I received from a representative at ES today:

"Although we never had any issues with the Nitrogen, at some customers request (who are familiar with inert gases) we decided to make the switch to Argon. The Argon molecule is a larger molecule which over time may give us less issues than Nitrogen. However, as I stated, we haven’t had any issues with the Nitrogen. We just need to watch and label our boxes better as we QC them."

This is as some have speculated, and (to me) it made some fiscal sense why the mismatched boxes and eyepiece lettering/stamping (costs money to throw out surplus boxes and eyepiece barrels, etc., so perhaps they opted to use what they had in supply). My only real 'gripe', if it could be considered such, is that either a paper insert to explain the ongoing program to convert and/OR something prominently featured on their website, which (at the time) still marketed the ES82 'Nitrogen' purged line of EP's... while I held in my hand one that said Argon. :foreheadslap:

I won't say 'mystery solved', as many solved this thru speculation or other sources of information. For me, it's nice to finally see something of an official word from ES on the matter.

To those that recieved some of the conflicting labeled EP's, enjoy the Nitrogen lettered, Ar stamped EP's while they last! In the future, perhaps it could be resold as 'Rare Edition ES82 Nitrogen/Ar eyepiece'. Purged twice, for good measure. :grin:

Well the one thing ES is good at is "purging" my wallet of greenbacks.

Im not a chemistry major, but I would have thought the size of the two triple bonded nitrogen atoms would be bigger than the single argon atoms.

I wish I could provide them with more opportunity to do so to MY wallet. My wife and 4 daughters do a right thorough job of this already. :crazyeyes:

I plan to do so! :cool:

Would be nice to know, however what's inside, Argon or Nitrogen.

That's strange... it's like the missing link in the evolution of the ES82 series. First all N2? Then your N2 Box, Nitrogen lettering with Ar sticker on EP. And my N2 box, with Argon lettering and Ar sticker on EP.


Speaking of the evolution of the ES82 series, before all this Nitrogen/Aragon business, there was the non-waterproof ES82:

82ES14mm mushroom type; 100ES14mm Nitrogen

It would be nice, however, if a paper insert explaining the transition were added... or at least something featured prominently on their website?


Including a note in the box would be an official admission of a snafu, doesn't look good marketing-wise, so they chose to answer inquires on the Aragon/Nitrogen matter individually. Just speculating..

Best,

My 11mm ES 82* and 8.8mm ES 82* are both N2 purged and my 6.7mm ES 82* and 4.7mm ES 82* are both Ar purged. Hope they last through and past their 5 year warranties.

I recieved 3 ES82* eyepieces from Astronomics about 3 months ago and they came as follows:

8.8mm-N2
6.7mm-AR
4.7mm-N2

All lettering and stickers match.

Same here, they must still have a stock of the older boxes though.

Argon is a larger molecule and therefore tends to leak out less.. as for the miss-labeled boxes/ep's i went through this with ES and with my local Astroshop, i had purchased an 11mm Ar but got got an EP with the writing on the EP saying Nitrogen purged with an Ar sticker in the recess... spoke to ES, they confirmed they switched to Argon but still had bodies left over with the Nitrogen etching.. they were willing to replace, and i accepted. Not really a collectible since there are quite a few that were shipped this way.. all new ones are properly labelled Argon

I purchased a 4.7 mm 82* several months ago. It came with the neat looking box and had AR on the box label. The eyepiece however had the N2 sticker on it. I have the 4.7, 8.8, 18, and 24mm 82* eyepieces and all have the N2 stickers.

I got my 8.8 ES today. It is marked "Argon Purged" and the AR sticker. But it is also marked "Made in China". Does that make it a collectors item??? Gerry

I have had mine for at least a year and a half. All gas indicators match the lettering. The labeling on the boxes match what's inside.

I just received my 6.7mm ES82 from Eyepiecesetc. It said on the website, as well as on the order sheet, that it is N2 purged.

Mine is Argon purged though. Not really sure if that matters. It comes in a neat skymap box though. My 18mm ES82 came in an old blue box and it is N2 purged.

All of the ES 82 degree eyepieces I bought are nitrogen purged.
