I was browsing the Internet this morning and happened upon a telescope sales site in Japan by Kokusai Kohki. To my surprise I find that they sell erfle eyepieces, apparently on a production by order basis. Time span a few weeks. From the pictures they look very much like those sold by University Optics. University stopped selling the erfle several years ago. I am including a picture showing the apparent cosmetic quality of these eyepieces and a list of what is available. Has anyone out there had any experiences with this Brand? What kind of optical quality do they have? It would be interesting to hear about them.
