Jerry's 12.5" F4.5 String-Strut is Complete . . .

Jerry's 12.5" String-Strut. Note the Telrad, Sky Commander and
Moonlite 2-speed 2" crayford focuser. The DEC and AZ motions
are just right!! Jerry lives in Birmingham, Alabama.


Detail of the Destiny 3-vane curved-vane spider. A Kendrick dew
solution is installed on the secondary. Not shown 
is the "focuser 
baffle" opposite the focuser.

The beautiful 12.5" mirror is center marked with a "donut"
for easy collimation. Note the Easy Transport Telescope
(ETT) intermediate ring and mirror cover.

A dual-fan sits in back of the 6-point mirror cell. I always
use oversized knobs for collimation and "feet" sothe
telescope can be stood upright more safely.
