PlaneWave L350 Direct Drive Mount
The L-Series 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 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 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. |

PlaneWave CDK 14" Fused Silica
The CDK (Corrected Dall-Kirkham) Optical Design is an innovative solution for unsurpassed astroimaging quality at an affordable price. The CDK telescope design provides excellent imaging with large format CCD cameras while remaining superb for visual use. The CDK design far exceeds the off-axis performance of most commercial telescope designs including the Ritchey-Chrétien design.
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 six times lower than Borosilicate 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 high melting temperature (~1,600 degrees 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.
This no-compromise design is unique in making the optical alignment forgiving and collimation very easy. This guarantees the user the best possible performance from the telescope. The end result at the image plane of the CDK design is no off-axis coma, no off-axis astigmatism, perfectly flat field (no off-axis defocus). The CDK design will give you pinpoint stars from the center to the corner of the field of view.
Features:
|
Carbon Fiber Truss Design |
Open truss tube design with carbon fiber frame minimizes thermal expansion which causes focus shift with changes in temperature. Carbon fiber truss design also promotes quick thermal cooling and provides a rigid, lightweight structure. | |
| 3D Printed Baffles | Planewave uses digital 3D printing technology to produce lightweight baffle tubes. 3D printers add successive layers of material to construct a baffle system with precision positioned internal stray light baffles to minimize vignetting and maximize image contrast. | |
| Dovetail Expansion Joint | Allows for the difference in thermal expansion between carbon fiber and aluminum. The expansion joint allows the aluminium dovetail expand and contract without stressing the carbon fiber lower truss. | |
| Cooling Fans | Three cooling fans blow air inside the back of the telescope. Internal diverting fins circulate air flow behind the mirror for even cooling to help the telescope reach thermal equilibrium quickly. The fans are controlled with PWI PC software with the optional Electronic Focus Accessory (EFA Kit). | |
| Delta-T Ready | For added dew prevention, the CDK14 is internally wired with polyimide film heater pads and temperature sensor, ready to be controlled with the optional Delta-T controller. |
