A 10" F6 with Conical Mirror for Dave . . .

The 10" Royce conical mirror on its cell.

The spider is a Destiny curved-vane spider.

A custom mirror cover is included.

Detail of the conical mirror. It has a center "donut"
for ease during collimation.

The photo, taken a near sunset, has an interesting quality.
The telescope is outside for a final "star test".

The rear showing the mirror cell. The conical mirror is
held in place with a center 1/2" nylon bolt, spring and nut.

Dave chose to use a Helical focuser. Nice!

The telescope is so light and the motions are so smooth
that I needed to install a "break" for some motion control.
It works great.
