A nice picture of Jay and his 14" Dobstuff/Zambuto. Here's his telescope set up along the road in Utah. Jay lives in Herriman, Utah.

 -- he's quite the "sketch artist" and many of his renderings are throughout his blog.

10" Ultra Nearing Completion . . .

10" Ultra for Manoj in Campbell, California. The focuser is
a Kineoptics helical. The telescope weighs 31-pounds
including mirror cover.

A closer look at the focuser and single-vane, curved-vane
"spider" by Destiny. Note the focuser baffle.
The rear of the telescope. A small counterweight
in the center of the mirror cell helps balance the scope.

The telescope disassembles for "airline carry on"
Those photos will follow.

The mirror is a 10" F4.5 with enhanced coatings.

The focuser is a Kineoptics Helical. Nice motion.

Now that I have the "spider" in-house, work continue's on Manoj's 10" F4.5 Ultra.

I was able to take the scope out "under the stars" this evening and set the height of the focuser. It is 44" from the ground at the zenith.

The spider is a "single vane" curved-vane by Destiny.
The "hanger" on the far side is for the focuser baffle.

A 12" F5 telescope is complete for Bruce C. in Glen Rose, Texas. The scope includes a Moonlite focuser, black powder-coated struts, Sky Commander with stalk and a mount for Bruce's Telrad.

If you look closely, you can the "strings" running from the top ring to the mirror box.

Under the stars, the scope performs beautifully. Nice!!

And a note from Bruce dated February 13, 2014:


Finally got to take the scope out tonight, first clear night in over a week, first with decent seeing and transparency in forever. You are absolutely correct, love the scope. Seems to hold collimation well, which is a blessing, as I still don't quite have the process perfected. Gorgeous views of M42, Double Cluster, numerous double stars, Jupiter with 4 moons, all in spite of a full moon.  I liked the 17T4 a lot, as you had suggested, but my favorite so far is the 26T5, along with the 9mm T6.  Moonlight focuser is very smooth; motions are also very smooth, easy to nudge, nudge, nudge along when viewing Jupiter.   Now, if I can just get the Moon and clouds to go away at the same time .

The Upper Ring for the 17.5" F4.5. The focuser is a Moonlite,

Moonlite truss blocks on the underside of the ring.

A 12" F5 for Bruce C. in Glen Rose, Texas is virtually complete. Here the Sky Commander stalk and computer system has been installed and configured. Once the telescope is assembled, I test the Sky Commander "under the stars".

The full-length struts are out being "powder coated".

Here the mirror cover has been completed.

Two "posts" and wing-nuts hold the cover in place.

This is an all Baltic birch cell with 3-point suspension.
More than adequate for a mirror of this size.

The rear of the 8" mirror cell. Plenty of ventilation.
