|Just about completed is Al's 16" F3.9 string-strut telescope. |
There's just a couple more accessories to add -- a primary
dew shield and dual- fan assembly. Out under the stars,
this evening, the scope performed like the beauty it is.
|A "powered" ground board is always a nice feature. The power source,|
a battery, can sit 12 feet out of the way.
|The power "distribution" on top of the ground board.|
|And the power control panel can accommodate 3 devices.|
|Dual fans for Al's 16" telescope.|

|A 10" f6 from Nova Optics for my new "personal" telescope.|
|The OTA for the 10" F6. Note the full UTA for this "strut: telescope.|
the focuser is a Moonlite 2-speed with a Destiny 3-vane curved-vane
spider. The secondary is 2" minor axis.

|Al's beautiful 16" F4 primary mirror. I've put a "donut" onto the center|
for easy collimation. The spider is an "observatory grade" heavy-duty
unit from Destiny with a Feathertouch focuser.
|The custom mirror cover in place. It's now time to "test" the strut lengths.|

|That's an "observatory grade" Destiny spider and Feathertouch|
focuser. The secondary mirror will have a "dew solution" affixed.
One of our customers, his 10" telescope and a great idea for a focuser baffle. LOOKS GREAT:
My 10" Dobstuff came with a small rectangular shroud opposite from the focuser. At home, I have various streetlights to contend with, and found this small shroud woefully insufficient.
It's made of ABS plastic, same as the shroud near the primary mirror that came with the scope. I measured the shape; there are notches for the spider vanes, a circle for the focuser, and an odd rectangle where my finders stick through. I sent the design to a plastics store to make the cuts, since I'm short on tools. I then spray painted the inside with flat black, and used velcro to hold the overlapping edge together. It attaches to the top ring via some hand screws, so it's easy to remove if needed.

|A 16" strut telescope for Albert in Appleton, Wisconsin. This |
telescope will sport a Feathertouch focuser, 3-vane observatory
grade spider, Easy Transport Telescope option and Sky Commander.
|24" altitude bearings will guarantee smooth motion and enough sticktion|
to keep the telescope in place between eyepiece changes.
|Also underway is a modification to Ken's 16" truss telescope. We're making|
this 6-tube truss into an 8-tube truss and adding a full upper tube assembly.
