Rancho Mirage Library and Observatory . . .

That's me and the new Rancho Mirage Library and
Observatory's 28" telescope. It's a beauty.

Just outside the "observing room" are 4 pads for amateur
astronomers to setup their own telescopes.

Another view of the 28" telescope by Planewave Instruments.

Primaries and Secondaries for David's 17.5" Truss Telescope . . .

An all aluminium 6-point cell is affixed to David's beautiful 17.5" mirror.
This, and all my mirror cells, are designed and optimized with Plop.

A beautiful 3.1" secondary on its holder. It'll be painted black
to minimize unwanted light reflections.

The "observatory grade" 3-vane spider and focuser bracket is
in place and near completion for David's 17.5" telescope.

Bruce's 6" Newtonian .. .

Bruce sent along a photo or two of his beautiful 6" Newtonian on our rocker box mount we made for him. I especially like the color scheme and graphics on the tube. note the nice Moonlite focuser and Telrad.  Bruce lives in Marintez, California. 



More on David's 17.5" F4.5 . . .

The large 22" altitude bearings and rocker box sides are in
process. These, plus the OTA components below, make
a good portion of the entire telescope.

The OTa components. this will be an 8-truss telescope design.

The OTA rings for David's 17.5" truss telescope now under construction.  
It sports a very nice Coulter mirror, upgraded secondary

A Little More for Bruce's Rocker Box ...

Now with the bottom of the rocker box installed.
I make the base a bit larger for stability.

Even though the rocker bottom is a bit larger,
it still only measures 19" in diameter.

A 6" Newtonian Rocker Box for Bruce . . .


A rocker box and altitude bearings for Bruce's 6"
Newtonian reflector. Bruce lives in Martinez, CA.

Bruce asked for a "little height" on the rocker
box itself. The custom color will be red mahogany.


An "example" of the rocker and
altitude bearings. This one is a bit
larger, having been built for an 8"


A 4" Refractor ...

Phillip, a "friend of a friend" brought over a 4" refractor for
an upgrade. So far, it's lookin' good.

Rick's 12.5" Kit is Complete.....

All the "parts 'n pieces" for Rick's 12.5" kit. Assembly, really,
is quite easy with instructions on my website.

I've pre-installed the mirror cell on Rick's mirror. It's a 6-point
non-flotation cell -- with the thick primary, it'll work perfectly.

I've also pre-installed the spider, focuser on its bracket and bracket
on the upper ring. The focuser is a 2-speed Moonlite crayford.
