Quote: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.That makes a lot of sense from the standpoint of manufacturing costs.

Quote:All of mine are N2 purged too, but I wouldn't worry about it. Nitrogen preserves tires just fine, it will also certainly be friendly to the glass, metal and rubber seals that make up ES eyepieces. It has worked fine for fog proofing rifle scopes, spotting scopes and waterproof binoculars too.Taras

Quote: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.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Quote:Well the one thing ES is good at is "purging" my wallet of greenbacks.
Quote:Quote: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. mark I plan to do so! Would be nice to know, however what's inside, Argon or Nitrogen.
