If there is sufficient interest, I am willing to hold an "eyepiece seminar" sometime this summer, when my workload eases a bit. I envision a couple of speakers, perhaps, on subjects like lens configurations, field-of-view, terminology, eyepiece history & mythology, etc., then a workshop where everyone gets to assemble their own eyepiece from surplus optics. I will choose the speakers. Then a star-party in the evening to compare commercial products and try-out everyone's home-made eyepiece from the workshop. If I can't procure the eyepiece parts free, there may be a small charge to cover those costs only. Any interest? Chuck __________________________________________________ Do you Yahoo!? Yahoo!
