I have one that looks like it has some growing *inside, between the elements.

 

I guess waterproof doesn't mean 'Airtight', but what funguses grow in argon?

 

Aren't these things supposed to be sealed?

 

I'm happy to pull apart to clean as I have the tools, but I wonder also if, like with the lens cell of an apo, there is a risk of 'decollimating' the EP through axial movement or rotation?

 

Anyone care to chip in?

 

Many Thanks

 

M

I have never seen a discussion about the lenses inside an eyepiece being rotationally oriented to each other. And with probably about 7 in your version, that would be a challenge!

 

I have taken apart TV Plossls before, and much simpler than yours. But the key, for sure, is careful disassembly so that you don't have glass, spacers and other bits spilling out on the floor. Mark each lens in sequence and orientation (front, back) and either take photos or excellent drawings of it as you take it apart, so that you can get it back together. You could put a rotation registration mark on them too, just for assembly ease of mind.

 

Good luck with this!  and keep us posted on your progress.

Sounds like the Argon is long gone from your "waterproof/airtight" ep.

Well, exactly. So is it a warranty issue then?

I assume you are talking about the ES82 30mm eyepiece in your signature. They carry a 

lifetime guarantee. I would give ES a call.

Yes sounds like the Argon has left town.  How old is the eyepiece?

What else could it be?

 

It certainly looks like it.

I neither see your eyepiece nor detailed description or photo. Also I know nothing about your qualification in the question. So it could be a little doubt in your diagnosis...

Can you try to post a pic of the stuff?  Might help others with same eyepiece...

Argon filled means airtight and airtight means waterproof, argon atoms being smaller than water molecules. Funguses probably don't do well with pure argon, which (being a noble gas) doesn't react with anything (unless under extreme duress) and therefore is a very poor material to fulfill respiratory needs. So, if there's fungus in there, that's a pretty good indication that you've got a leak.

 

If it were me, I'd contact ES and see about sending it back or getting it cleaned / reported / replaced / whatever. There is a lifetime warranty as I understand it.
