Chuck- I'm interested in the proposed eyepiece seminar, and would gladly pony-up $15. I would like to have your speakers address the applicability of different designs of eyepieces for different telescope designs, such as very long vs.very short focal lengths. Which eyepieces offer the most benefit for a 20" f4, or a 8" f6, or a 4" f15?

I'll start seeing what optics are available, and gathering materials. To keep costs down, we'll probably build a Plossl or true symmetrical. If I can find some inexpensive triplets, the ortho can be explored. I may be able to offer kits of both designs, wait and see.
These "kits" will cost me about $15 each; is everyone who wants to participate able to pony-up fifteen bucks? I will make no profit on this endeavor, but must cover costs.
Although we probably will NOT use wood for a housing, optically we will be building something similar to the "Homemade eyepieces" I described in S&T a couple of years ago (Feb. 00).
Let me know if there are any particular questions you would like the speaker(s) to address.
Thanks!
