PlaneWave Instruments brings a fully automated observatory class telescope to the market in the CDK700, a 0.7 meter, Alt-Az telescope system. The CDK700 combins the revolutionary optical system that founded PlaneWave Instruments with a brand new innovative alt/az mount technology that sets a new standard for small observatory telescopes.

CDK700 Features

  • Pinpoint stars out to a 70mm image circle
  • Dual Nasmyth focus
  • Direct drive motors on each axis
  • Hi Res Encoders on each axis
  • Zero backlash
  • Zero periodic error
  • PointXP Mount Modeling Software
  • Field de-rotator / field framing
  • Stiff, smooth, quiet and extremely fast drive system

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.

CDK Optical Design: Our design produces a flat, coma free and astigmatic free field of view. Since the secondary mirror is spherical, centering is very forgiving, which means it is easy to get the telescope optics aligned for optimum performance, this is not the case for most high-end astrographs. The end result at the image plane of the CDK design is no off-axis coma, no off-axis astigmatism, and a perfectly flat field, all the way out to the edge of a 50mm image circle. All this means, the stars will be pinpoints from the center of the field of view out to the corner of the field of view.
