Chuck, Sorry for the late input on the eyepiece seminar idea. I have been under the weather lately (long story). That and I am still in shock over the tragic events of the weekend. Reading all of your posts have certainly helped focus my thoughts this week. Patrick W. sure vocalized all of our thoughts that next day, thanks a bunch. Down to business... I have improved my Excel spreadsheet on eyepiece design. I would be more than willing to release it to the eyepiece seminar group for their free use. I would rather not release the version that I gave to you just because it is not as polished as I wanted it. I'll email you the "latest greatest" as soon as I tweak it a little more and include a text file to explain its use. Bye the way C.H., what happened to your webpage on eyepiece design? The old link doesn't work and a modest search for it only shows your wooden telescope making pages. That e.p. design page was great and to the point. Include me in on the fun. Tnx es 73 de n7zi Gary Liptrot Why buy something for ten bucks when you can make it for a hundred...

There are far fewer appropriate lenses in the surplus market today, than there were 3 years ago when I was heavily involved in eyepiece making. I did find some lenses good for symmetricals & Plossls, as well as a couple of triplets that might work for orthos, however prices have risen in the last few years. If it looks like lens prices alone will exceed fifteen dollars, I'm less inclined to make the effort. I would have to sell all of these kits to make it worthwhile, and once you get around $20-$25, there isn't much motivation to make your own eyepiece other than curiosity. Bill Kelley has contacted me regarding some nice little achromats that will work, if we can get enough of them. (Thanks, Bill!) My own parts bins have only enough lenses for perhaps four or five eyepieces right now. Stay tuned. C. __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful.
