for Mike in Oberlin, Ohio.

17.5" Rocker Box for Chris . . .Thris

23" Altitude Bearings and lower profile rocker box removes
75% of the weight. In addition, a Sky commander was added.

Chris' 17.5" Rocker Box Upgrade . . .

Greatly reduced size and weight of Chris' 17.5" F4.5 Truss Telescope.

I'll install a Sky Commander for this telescope.
Nice!!

If the altitude bearings are removed -- they'll be held in place with
bolts with wing nuts -- the mirror box will "nest" into the rocker box.

Joe's 14" and Chris' Rocker Box . . .

A look at the new rocker box for Chris' 17.5" truss telescope.
Quite a difference. It will now that 23" altitude bearings instead
of the older 10" size. 

Joe's 14" rocker box and altitude bearings start coming together.
The bearing are 21" in diameter -- the perfect size for a 14".

17" Mirror Box/Altitude Bearings . . .

Chris, in Ontario, California, and his traditional 17.5" truss telescope.
The balance isn't too good and the rocker box is VERY heavy!!

I've managed to fit this project in between another two. Here, I'll add larger
altitude bearings with dramatically reduce the size and weight of his
rocker box.

Larger altitude bearings will greatly improve the balance and
general handling of his telescope. More photos will follow.

A 14" Truss Telescope . . .

Underway is a 14" F4.5 truss telescope for Joe M. Here
the Upper Tube Assembly (UTA) is in the early stages of construction.

The 14" UTA with baffle installed.

And, the Mirror Box rings (excuse the "false color" --
it must be the lighting!!
