PlaneWave Instruments is proud to introduce its new L-Series direct drive mount system. Offered in Alt-Az or Equatorial configuration. The L-Series comes in three models; the L-350 capable of holding 100 lbs; the L-500 designed for the CDK17/20 that can hold payload of over 200 lbs. The L-600 is ideal for the CDK24 and can hold up to 300 lbs. All mounts are designed and manufactured by PlaneWave Instruments with zero backlash and zero periodic error, virtually silent motion and slew speeds of up to 50 degrees per second!
Description
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 traditional 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! For added flexibility, the L-Series mounts can be installed in either Alt/Az, or equatorial mode with the optional wedge accessory.
L-500 Mount Features:
- Load capacity of 200 lbs (90 kg)
- 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. |
