I have just been listening to the other members and gleaning from their Wed, 23 Dec 2009 03:39:01 GMT rwiederrich http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/306 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/306 Yes...Tim's single folded design does look easier and less costly in mirrors. Nearly a newtonian design with the small diagonal that send the light into the Tue, 22 Dec 2009 23:08:26 GMT KP3FT http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/305 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/305 Thanks! I've always wanted a good quality 6" f/15 or f/20, but the length isn't very practical to take out to star parties. The folded design is perfect.

We have had several members make folded refractors. I'll do a bit of searching myself. The design for them doesn't Mon, 21 Dec 2009 17:23:41 GMT KP3FT http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/303 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/303 Hi all, just joined the group. I did a search for "folded" in the forum, but didn't see anything, so I was was wondering if there are any online plans for a Sun, 20 Dec 2009 17:38:11 GMT dawsonian2000 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/302 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/302 Thanks for kind words and support, Rob! As for my next project, I am planning to build a 6" f/5 Fork Mounted Newtonian. Wish I had the space for an 8" f/12.

It is just these minor setbacks that keep us on our toes and keeps our Sat, 19 Dec 2009 13:15:27 GMT schupmannmedial http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/299 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/299 Engineering failure. After assuming that my engineering was sound, I have been rushing this scope project through for my yearly Star Party that happened last Fri, 18 Dec 2009 18:48:43 GMT rwiederrich http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/298 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/298 Mel....again thanks for the wonderful recognition.... It was your application of growing skills that pulled this wonderful scope together.

I'm glad my comments and advice were found to be helpful.

It took me a year to pull off another telescope build. I thought my 10" f/5.6 Newt was a challenge, but when I Fri, 18 Dec 2009 10:24:16 GMT dawsonian2000 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/295 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/295 Hello HomemadeRefractorTelescopes Member, Thought I would let you all know that despite not adding recent photos to my album on this group (which I regret and Tue, 15 Dec 2009 23:50:55 GMT Doug http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/294 http://tech.groups.yahoo.com/group/HomemadeRefractorTelescopes/message/294 My friend and collaborator Sheldon Faworski did the machining.
