If the eyepiece is optically sound,  If you have a useless filter around try screwing and backing off and screwing some more.  Hopefully, it will get all the burrs off.  Call ES first though, they might be ok with trying that before returning.  I'm beginning to wonder about ES QC....

If its optically good, it might be worth it to keep it if ES approves it, what ya got to lose?

I bought one of the 52 deg 6.5mm for my son. The one I have looks ok but I tried threading a cheap Meade branded moon filter on it and while it threaded on it seemed a little rough and wouldn’t thread on all the way. For this focal length it’ll probably never use a filter but ...

Send it back. If people keep eyepieces with problems, they'll have no incentive to straighten out their quality control.

I'd return it too.  And, I hate returning things!  

 

This eyepiece looks as though someone already had a rough go with it so I'm thinking it looks like a return.

Yes, I'd personally return it and ask for a replacement.

I doubt you'd even have to return it.  Just send them that photo; I'm sure they'll just send you out a replacement.

My ES eyepieces are perfect. Sometimes one can be just unlucky...

Not speaking for ES, but having spent the last 17 years of a 30 year career in a foundry. 

 

The last several years we were shipping thousands of parts daily. We had 3 trained inspectors including myself.

 

There is absolutely no way in China your going to catch every part that's defective.

 

In a perfect world maybe....but not in the real world. The threaded barrels are probably made in one plant, while the housing are made in another, and the lenses are made in another.

 

My experience with ES has been extremely good. That's not saying that a defective part cant slip by.

 

Let them know, really.....we in quality at our foundry took returns seriously.

Judging from the picture , it looks very much like casting defect, it could be a machining error as well. but my money is on a casting error, most likely  a misrun of sorts, that the machinist tried to machine out.

Contact ES.

I have EPs that I cannot thread a filter all the way in. This doesn't effect the use of the filter as it still hangs onto the eyepiece. I'm not sure if it's the fault of the EP or the filter and frankly, I'm too lazy to find out....

Poor machining ! Looks like it was damaged when chamfering .

I've ordered a bunch of ES eyepieces recently because of the sale and they have all come in good shape. The HRCC I got had a little dust on it that I didn't notice until I pointed it at the moon and looked down the tube when changing eyepieces. But it cleaned off easy enough and I went ahead and kept it. Wasn't as nearly as bad shape as that 12 mm that needed to be replaced.

Wanted to follow up on this after threading the filter on and off a couple times and wiping the threads on both pieces it threads on fine now. Its not as precise as the ES82's as those will thread on all the way with a flick of the fingers. I echo what other are saying to just contact them and they'll replace it. If you ordered from a dealer (or direct from ES) ask them to send you a call tag from UPS/Fedex and ask them to get the other one shipped out as soon as the call tag is scanned by the shipper. I've done this a couple times and it speeds things up. These are really nice eyepieces for the money and are worth the hassle

I just got a 6.5 mm that is in the same condition as yours but mine won't thread properly even after wiping the threads. I can thread on a filter but it only threads on a half a turn. I'm a bit on the fence about sending it back but worried a half threaded filter might fall off unexpectedly.

While ES quality appears to be a mixed bag, I like their daring for the exclusive to them models.

 

Many have and do enjoy the 25/100, 92s, 30/100, 9/120 etc. Those eyepieces are ES signature models, catering to people looking for something no other makers have touched on.

 

More 92s, and equivalents of the longer FL Masuyamas are what I hope for from ES.

The replacement eyepiece arrived today in the form of a 9mm instead of the 6.5 that I purchased. And so the story continues .Dandy ES !
