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.
PlaneWave CDK400 Telescope System f/6.8 consits of the CDK17 and the L-500 Direct Drive Mount with integrated high resolution encoders and high speed slewing.
The PlaneWave Instruments CDK17 is a 17 inch (0.43 m) f/6.8 Corrected Dall-Kirkham Astrograph telescope. The CDK17 covers a 70 mm field of view without any field curvature, off-axis coma, or astigmatism. The instrument weight is 94 lbs (43 kg) and comes standard with a back plate retaining ring ready to accept the focuser of your choice.
The abbreviation CDK stands for the optical system of the PlaneWave astrographs - a Dall Kirkham Cassegrain with a optical correction unit.

Fused Silica
Fused Silica is a synthetic amorphous silica glass of the highest purity and one of the most transparent glasses made. The optical and thermal properties of fused silica are superior to other types of glass due to its purity. Its transmission and homogeneity exceed those of crystalline quartz without the problems of temperature instability inherent in the crystalline form. Fused Silica has a coefficient of thermal expansion six times lower than Borosilicate (Pyrex) glass, which means that as fused silica cools down, it preserves its shape to a high degree of accuracy. This translates into consistent optical performance and unchanging focus over temperature changes. With its high melting temperature ()~ 1.600 degree Celsius), a very low coefficient of thermal expansion and resistance to thermal shock, fused silica is the material of choice for professional observatories as well as various scientific applications.
The L-Series combines versatility, simplicity and affordability by combining all the technology of our Observatory class telescopes into a compact stand-alone mount.
The mount is equipped with direct drives motors as well as high-resolution encorders. The software is ASCOM compatible and the direct drive motors can move the telescope at incredible speeds for tracking satellites.
In its Alt/Az configuration it is considerably more compact than its equatorial counterpart, allowing a larger telescope to fit in a smaller enclosure. The mass it takes to make a rigid alt/az mount is substantially less, leading to cost savings. 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.
L-Series 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
Latitude Range: 0 to 90 degrees, Northern and Southern hemispheres
Enclosed electronics
Through the mount cabling: Access panels in the fork arm and azimuth axis allow for camera equipment cabling through the inside of the mount.
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
Control System
User Interface: PlaneWave Interface 4 (PWI4) Control Software with integrated PointXP mount modeling software
Slew Rate: 20 degrees per second (standard); 50 degrees per second (maximum), both axes
Home position sensors are included allowing the mount can find its home position on power up.
