My new 2" Orion filter would not thread on more than one turn in any of my eyepieces ... I had the same problem, Orion and Baader 2" filters. They would not thread correctly on my ES eyepieces, Astro-tech Titan II eyepiece, William Optics diagonal, nor Televue Paracorr. My Lumicon filters threaded on all of the above easily. This tells me that the problem is with the filter manufacturers. You might pay more for Lumicon, but they work.

The filers are lumicon, baader, and zuhmell.

Quote:I tested my filters on an ES 14mm 100' and they all work fine as well. To be fair here to ES I have had other EPs which were a bit sticky with filters - Baader Hyperions for instance.It seems there is a variation in thread pitches in astro filters and barrels - why am I not surprised - hardly anything in astro ever fits together the way you might wish for but thats hardly the fault of ES alone.

Quote:Anyone having trouble fitting 2" filters on ES eyepieces?I just received my new ES 82°-30mm eyepiece and am having trouble threading any one of my 2" filters. I own several other ES eyepieces but this is the only 2" ES eyepiece I own so I can't compare. The filters thread fine on all my other 2" non-ES eyepieces.I checked for barrel roundness and it's fine. I noticed the threads seemed very fine and did not seem to be cut deeply. That seemed to be the problem.I will contact the vendor this morning to see if this can be exchanged. I was just wondering if anyone else had a similar problem.Thanks!
If I don't see you in the future maybe I will see you in the pasture.

Quote:Hey Tank, I bought one of the old style 30mm ES 82 series eyepieces from Woodland Hills. I used the link you provided. Thank you for the link! We now return to our regularly scheduled programing.

Quote:Quote:I think ES eyepieces are excellent in all regards except they screwed up their filter threads. Certainly isn't what I've experienced. As I mentioned, all my filters screw on my ES30 very smoothly. There must have been a few that the filter threads are not up to standard, but that doesn't apply to all ES eyepieces. Also, with their warranty, buyers can certainly be covered in case their eyepiece threads are bad. As mentioned, sometimes the fault lies with the filter, not the eyepiece. Orion was one that was very tempramental to thread onto all of my eyepieces, including ES, TV, Pentax.
Quote:It's not ES, at least in our case. We got the 2" Orion Ultrablock and 13% moon filter, two of each for BVing. Amongst these 4, one of each pair will thread onto our ISTAR star diagonals and 31mm Baader Aspherics, but the other two filters will not.
Quote:Time to resurrect this thread! I just tried threading my 2" Orion Ultrablock onto my 34mm ES 68 and it was a bit touchy at first, but once I got it to catch, it threaded all of the way on!Cheers,
Quote:I think the question to be asked is why there is no international standard for eyepiece filter threads, not why brand X filter doesn't fit brand Y threads.
