The PlaneWave RC700,a 0.7 meter Alt/Az telescope system with Ritchey-Chrétien (RC) optics. PlaneWave have combined Ritchey-Chrétien optics with PlaneWave's direct-drive alt/az mount technology to set a new standard for research-class observatory telescopes.
PlaneWave's CDK astrographs have become the telescopes of choice for universities, industry, and astrophotographers around the world. Now PlaneWave offers the PW-RC series to meet the custom needs of the scientific community. More about the optical design (Verlinkung).
The PW700-RC in its native format (no field flattening lenses) uses only mirror with reflective coatings. This can be useful when making observations primarily on-axis and wide field imaging is not a concern.
With high-resolution encoders providing the feedback for the direct drive motors, not only will the telescope track without periodic error or have any backlash at all, but the mount will be able to counter against wind gusts. The direct drive motors can move the telescope at incredible speeds for tracking satellites or just to minimize target acquisition time.
Benefits of Nasmyth Focus: The Nasmyth Focus is along the altitude axis so there are virtually no balancing issue as you change out equipment. Eyepieces remain at a constant wheelchair-accessible height, greatly simplifying access to the telescope for public observatories. The rotating tertiary mirror allows you to switch from one Nasmyth port to the other in just seconds, allowing observers to easily transition between imaging and visual use
