PlaneWave Instruments brings a fully automated observatory class telescope to the market with the PW700-RC, a 0.7 meter Alt/Az telescope system with Ritchey-Chrétien (RC) optics. We have combined Ritchey-Chrétien optics with PlaneWave's direct-drive alt/az mount technology to set a new standard for research-class observatory telescopes.

CDK700 Features

  • Ritchey-Chrétien optical design
  • Dual Nasmyth focus, allowing simultaneous mounting of two instruments or easy switching between visual and imaging use
  • Direct-drive motors on each axis for smooth, fast, and virtually silent movement of the telescope
  • High resolution encoders on each axis for precise positioning
  • Zero backlash
  • Zero periodic error
  • PointXP Mount Modeling Software
  • Field de-rotator / field framing

An alt/az mount is inherently more stable than an equatorial mount as there is no cantilevered mass, nor are there any large counterweight protruding that are very dangerous in a public observatory. The mass it takes to make a rigid Alt/Az mount is substantially leading to cost savings. There is no dealing with balance changes as you cross the meridian or meridian flips that German Equatorial Mounts have to deal with. You can image from horizon to horizon continuously if desired. Alt/Az is more intuitive to use and there is no polar alignment needed. Besides, it is the way the big boys do it.

Benefits of Nasmyth Focus: The Nasmyth Focus is along the altitude axis so there are virtually no balancing issue as you change out equipment. In addition the CDK700 comes standard with a field rotator / field framer.

Direct drive motors and encoders: Direct Drive motors means that there are no gears which cause backlash and periodic error. With the 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.

Rotating Tertiary Mirror: The PW700-RC includes an integrated rotator for the tertiary mirror, with magnetic locks to position the mirror precisely for either Nasmyth focus position. The rotator can move from one port to the other in under 10 seconds.
