|
Robofocus control unit mounted with Velcro to OTA. Remote focusing control unit allows for visual observing with zero vibration.
|
|
Robofocus controlled secondary focusing mechanism with secure mounting of Robofocus motor.
|
|
Stainless steel focusing shaft producing zero image shift and zero backlash keeping star centered during computer controlled focusing methods.
|
Lightweight carbon fiber truss design to securely hold head-ring and reduce thermal expansion.
|
|
Concave Pyrex mirror and carbon fiber truss design keeps focus over 40 degrees Fahrenheit.
|
|
Variable speed control unit for vibration free cooling. High speed for initial cool down, and low speed to create consistent airflow over primary mirror surface.
|
Standard Losmandy style dovetail for easy mounting to any mount.
|
|
Brilliant optics, flexure free truss design, low cost OTA for high-resolution, large chip CCD cameras.
|
|
Knife edge baffled and flocked primary mirror reduces off-axis light and increases contrast. Ideal for light polluted locations.
|
Up to three additional Losmandy dovetails can be added to left, right and top of OTA for additional telescope mounting.
|
|
Visual configuration with remote focus control for crystal clear, edge to edge visual observing through the eyepiece.
|
|
3" Pyxis rotator threads directly to 3" Celestron male threads.
|
2.7" AP .75X telecompressor to reduce focal ratio to F9 while maintaining flatness of field.
|
|
AP Telecompressor installs recessed into rotator for precise placement of focal reducer.
|
|
SBIG ST10XME with AP Telecompressor provides 0.5 arc-seconds per pixel image scale at F9. Rotation makes it easy to find a suitable guide star
|
Astrodon MOAG off-axis guider threads into 2.7" AP adapter for the Optec Pyxis rotator.
|
|
SBIG STL11000 threads directly to the Astrodon MOAG for a 100% flexure free image train.
|
|
SBIG ST402XME off-axis guide camera installation. The off-axis guider can also be used with the remote guide head for STx and STL series cameras.
|
Additional OTA's mounted for wide field imaging and an external finder scope.
|
|
Classical Cassegrain F12 designed OTA to provide coma free imaging with large chip CCD Cameras.
|
|
Truss design reduces vibration caused by wind.
|
Lightweight carbon truss design for maximum portability.
|
|
OTA (without accessories) weighs only 27 pounds.
|
|
Lightweight allows for mounting on Losmady G11, Titan, AP900, AP1200, MI-250 and Paramount ME mounts.
|
Super strong frame and truss design measures less than 20 arc-seconds of flexure from 50-90 degrees altitude and 360 degrees azimuth.
|
|
Super sharp optics and open truss design produces sharp stars with no edge effects and no chromatic aberration.
|
|
Proprietary primary mirror mounting results in zero mirror movement producing perfectly round stars.
|
|
|
|
Clean, simple design is attractive and functional.
|
|
|
F12 design with STL11000 produces coma free flat field and a 32.5 x 21.6 arc-minute field of view at 0.5 arc-seconds per pixel.
|
|
3800mm focal length produces 0.5 arc-seconds per pixel with 9 micron CCD cameras.
|
|
Knife edge baffled and flocked secondary mirror reduces off-axis light and increases contrast.
