Upper Tube Assembly for 17.5" F4.5 telescope



I've been working on a 17.5" F4.5 for Brian in Dartmouth Nova Scotia, Here's a picture of the UTA (upper tube assembly). The telescope is coming along nicely.

Here you can see the Moonlite 2-speed, 2" focuser in place. The spider is an observatory grade curved-vane  Destiny.

The finder-board still needs to be added.

A 13.1" F4.5 for William in Novi Michigan.








Just completed is a 13.1" F4.5 with a Coulter primary and secondary mirror. The optics have new coatings and perform nicely under the stars. Note the Sky Commander and dew shield. The focuser is a nice 1-speed 2" crayford. A red dot finder is mounted on the top strut for aligning the Sky Commander.

Russ C. from Sacramento CA picks up his 13.1: telescope.










Russ C. from Sacramento, CA. came by to pick up his 13.1" telescope. We "test drove" the scope in the backyard. Using the Sky Commander, we easily located and viewed M13, M92, M88, Saturn and other DSO's. It was a great evening for both of us.
