|I have a very nice 10" F3.9 mirror and telescope|
under construction. The focuser is a Kinoptics
helical. This telescope will be a bit different with
a 6-strut round tube assembly. Keep an eye here.
This telescope is for sale!!
|Under construction is a 10" "string-strut" for Bruce. This is|
a remake from an older, much heavier, F6 Discovery. The
optics are beautiful. This will be the ETT design.
|A 12" kit is completed for Patrick in Philadelphia. This was a|
"partial kit" as well as a "second". But, it's all complete and ready
to go. Some of the parts are from different telescopes, but it
complete and will make a great strut-telescope!!

|John nice 8" F4 OTA is completed. Note the Telrad mount, Moonlite focuser|
and Moonlite 4-filter slide. The OTA is 30" tall and weighs just 22#.
|A Losmandy dovetail plate will fit on any compatible mount.|
|A single 12Vdc fan will help cool the nearly full thickness primary.|
|The two-speed 2" Moonlite focuser is a beauty.|
|The "standard straight-vane" spider is spring loaded for easy collimatin.|

|Now the length of the OTA is calculated, it|
just needs to be "tested"under the stars. Note
the "adjustable" struts in case minor adjustments
need to be made. The mirror cover is installed.
|Without the mirror cover, but with the|
Moonlite focuser and filter slide ready
for testing tonight. the OTA is a mere 30" long.
