These are the projects lined-up for which I have all the components and/or raw materials already on-hand: Various 50mm short-focus "finders", except with 1.25" r&p focusers.

Plus I can work on them in the basement in winter. I also like small refractors! The larger sizes must be done in the garage, and it's still too cold to spend much time in there. This is probably going to be a popularity contest for telescope type, lets see what happens.
Do the one you'll use the most. I must admit, though, that the 5"RF refractor sounds interesting. ________________________________ From: Chuck Hards <chuck.hards@gmail.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Tuesday, January 24, 2012 1:55 PM Subject: [Utah-astronomy] Telescope vote With the sunspotters out of the way, I've got a dewcap and couple of parallelograms to make for friends, but no telescopes on the workbench for myself.

I also have the Jaegers 6" f/5 doublet, but I'm not buying the tube for a few more months. It's calling to me, though! On Jan 24, 2012 3:48 PM, <erikhansen@thebluezone.net> wrote:

When I built my refractor (the one at SPOC) I ended up with a piece of aluminum tubing which, if memory serves, was about 8" in diameter and a couple of meters long. Anyone interested in making a scope out of it? patrick
If it was 7" tubing, I'd take it off your hands. 8" tubing would be perfect for a 6" Newtonian, however. On 1/25/12, Patrick Wiggins <paw@wirelessbeehive.com> wrote:

As I mentioned before, I have tubing for 6 and 5" Jeagers but just enough for dewcaps. Yours for the asking.

Thanks Erik, I've got tubing for the 5", but none for the 6" yet, if you are coming to L&O next month, bring what you have along and I'll see if I can use it. On Wed, Jan 25, 2012 at 9:32 AM, <erikhansen@thebluezone.net> wrote:

I'm sure we will run into each other some time. Not sure about L&O yet, with the snow comes out of town guests to ski.
