CDK600 (.6 Meter Telescope System)

Part#: 240130

Price: $75,000.00

Based on the technology of our PW-1000 (1-meter) Observatory telescope, PlaneWave combines its revolutionary optical systems with its brand new innovative L-Series direct drive mount that sets a new standard for small observatory telescopes.

Also available with Ritchey-Chrétien (RC) optics and Fused Silica glass

CDK600 with Optional Equatorial Wedge 

The CDK24,  24 inch (0.61 m) f/6.5 Corrected Dall-Kirkham Astrograph telescope has a dual truss design, with 3 cooling fans for the back of the primary mirror and 4 fans for the front surface of the primary mirror. The CDK24 covers a 70 mm field of view without any field curvature, off-axis coma, or astigmatism. The instrument weight is 240 lbs (109 kg) and comes standard with a back plate retaining ring ready to accept the focuser of your choice.

       New Fused Silica mirror option available on all  CDK and RC models           

                                        240130Q - CDK600 Fused Silica - $85,000

The L-Series mount combines versatility, simplicity and affordability by combining all the technology of our Observatory class telescopes into a compact stand-alone mount.   In its Alt/Az configuration it is considerably more compact than its German equatorial counterpart, allowing a larger telescope to fit in a smaller enclosure.  Unlike German Equatorial mounts, there are no meridian flips to deal with, and no  large protruding counterweights to create a dangerous hazard in a public observatory. Alt/Az is more intuitive to use and no polar alignment is needed. Besides, it is the way the pros do it!

L-Series Mounts Features:

  • Direct-drive motors on each axis for smooth, fast, and virtually silent movement of the telescope
  • Slew speeds up to 50 degrees per second
  • High resolution encoders on each axis for precise positioning
  • Zero backlash
  • Zero periodic error
  • PointXP mount modeling software
  • Enclosed electronics
  • Through the mount cabling

FEATURES:

Direct drive motors and encoders Direct Drive motors and on-axis encoders eliminate the need for  gears, thereby eliminating backlash and periodic error. With high-resolution encoders providing the feedback for the direct drive motors, not only will the telescope track without periodic error and backlash, the mount will also counter wind gusts with precise servo feedback.  
Incredible Slew Speed The direct drive motors can move the telescope at speeds up to 50 degrees per second for tracking satellites or just to minimize target acquisition time.  
Dual mounting bracket PlaneWave style mounting bracket to hold CDK17/20 onto inside of fork arm with additional option of mounting a scope on the outside of the fork arm. Optional dovetail clamp required.  
Azimuth dovetail balance system For precise center of gravity balance whether in Alt-Az or Equatorial configuration  
Through the mount cabling Access panels in the fork arm and azimuth axis allow for camera equipment cabling through the inside of the mount.  
Proven CDK700/PW1000 Technology The L-Series uses the same proven technology as the CDK700 and 1-Meter PW1000 which are being used in Universities round the world.
