Threaded Reticles ??

Does anyone sell optical reticles that are threaded for use with you own 1.25 EPs? All I have found so far are complete eyepieces w/reticles. A nice laser etched glass crosshair would be perfect for my needs.

My Antares finder has an 1.25 EP with a cross hair that appears to be fishing line strung through four holes in the threaded collar. Since the line goes all the way through the collar it prevents the collar from threading fully into the barrel. The end result is that I cant acheive focus on a star and the reticle at the same time. Its a great finder but the cross hair is so out of focus you cant really use it.

Any ideas??

Thanks,
Mickey

Have you looked at Edmunds Industrial Optics' selection of reticles? I don't think they have any threaded inserts as you describe but they do have various types intended for use within microscope eyepieces. Might at least want to talk to their customer service people.

I have the same problem with my Antares finderscope - plus I have examined two others Antares finders it was also impossible to achieve focus on a star and the reticle at the same time. It seems it's a ''feature'' of the EPs that come with Antares finders. Anyway, it's not a very good EP.
I have bought a screw-in metal filter-type ring with a laser-etched glass reticle from Mike Spicer, a member of Astromart (see ad at http://www.astromart.com/viewad.asp?cid=165236). Beware, however, that this reticle causes a lot of vigneting in my Celestron 26mm plossl. See photos.
