|Katie, a teacher in Arkansas and her astronomy club will|
assemble a 10". Here the OTA rings are close to completion.
This complete kit will include everything they'll need to
assemble a working telescope.

|Conical mirrors are not at all usual. Here's a 12.5" version. They are mounted|
on the mirror cell with a simple 1/2" center bolt. Very nice.
|Note the conical mirror is thinner at its edge and gets|
thicker and heavier at the center. The flat spot, in
the center, is how it settles onto the mirror cell.
|Mounting hardware and instructions. Easy!!|
|The primary mirror in place on the mirror board.|
|The rear of the mirror board. Rubber feet for putting the|
OTA on the ground
|An interesting view of the conical mirror installed on its cell.|
|The mirror cell on the mirror board. The collimation bolts|
are 5/16" with large knobs for easy adjustment.

what a blast it's been getting this together, your workmanship is spot on, the material and hardware is high quality, and it's been great family fun with my wife and son lending extra pairs of hands when needed. What I've observed telescopically looks great in my amateur opinion. I mostly took your recommendations as to eyepieces, and sprang for a paracorr too. I might make one more length adjustment after experimenting as I did with different lengths of PVC pipe but I think we're pretty close. Have a good week.

|Here's the OTA components for Jim's string-strut telescope. The|
primary for this telescope is a "conical mirror" -- Nice!!
|Jim sent along his spider, focuser. The other components, in|
boxes, are his Rigel and Sky Commander.
Jim lives in Boligee, Alabama.

|While working on Joe's 16" telescope I made|
some end-tube rings for his 6" reflector. They're
made with Baltic birch and stained Ebony.
|The 16" mirror and cell. No clamps, just a bit of silicone at 120-degree|
intervals on the mirror cell. Note the eyepiece tray.
|A beautiful F4 primary mirror make up this extra nice telescope.|
|The focuser is a Starlight Instruments "Feathertouch" with integrated|
|Here the "truss section" has been removed for ease of transport,|
storage and assembly. Note the encoders for Joe DSC system.

I finally got some clear skies with little wind to get the telescope out for first light. My wife Tammy says The Orion Nebula was the best she has ever seen. The Trapezium was clearly resolved with my 32 mm Optiluxe (~52x) and with the O3 filter, we couldn’t get all the nebulosity in, and it was bright with lots of detail. We got M81 and M82 in the same field of view as well as the Andromeda complex. Tammy had me take off the coat because it was reflecting. I didn’t last long. It is 23 here in Prosser. Thanks for the great telescope!!!!!
