MATERIALS
Aluminum or carbon fiber truss tube. Each OTA is CNC machined to the highest tolerances and is computer optimizing for
lightweight operation with structural rigidity.
The primary mirror support system, secondary mirror support
system, spider as well as internal baffles, front & rear rings
and all small parts are fully CNC machined from aluminum,
stainless steel or brass.
DESIGN
The primary mirror support cell has absolutely no mirror-shift
or mirror-flop. The fixed primary mirror also has axial and
radial support and the unused outer portion of the primary
mirror is masked.
The primary mirror support and rear assembly are designed to
provide excellent ventilation and removal of internal residual
heat. Air circulation is accomplished via three axial fans.
Included is an external on/off and speed control for the fans.
Three adjustable rear assembly openings provide thermal convention adjustments to the primary mirror.
Three point collimation of the primary mirror, each can be
locked into place once collimation is achieved.
Fine adjustment settings for focal plan perpendicular on optical axis.
Computer optimized ray traced baffles on primary and secondary mirrors. Baffles are designed with internal micro baffles.

The OTA’s back-focus can be adjusted by shifting the secondary mirror shifting along very high precision guides. Typical settings are +/-10 mm (+/- 70 mm of back focus length) to allow
the user to achieve the for highest optical performance.
Fine adjustment for secondary spider centering.
Very thin yet strong four vane spider support.
Simplified three point secondary mirror and primary mirror
collimation.
The light path is fully baffled and coated with a very high quality opaque paint to provide the highest degree of protection
from stray light.
