The PlaneWave L-600 is an alt-azimuth, single-fork arm style mount that is capable of carrying a total payload of 136kg/300lbs. This mount therefore can easily carry a PlaneWave CDK24 or other similar size (or smaller) scopes and their accessories (e.g. camera, filter wheel etc).
PlaneWave L Series Mount with a CDK Telescope mounted on it.
The mount combines versatility, simplicity and affordability by combining all the technology of PlaneWave's Observatory-class telescopes into a compact and stand-alone mount and is a breakthrough in mount design, specification and features for the price.
The L-600 mount uses a direct drive motor system with high resolution encoders on both the RA and DEC axes that results in zero backlash and periodic error. The mount can slew at speeds from 20 degrees to up to 50 degrees per second!
The mount is offered in an Alt-Az configuration (or Equatorial with the optional Equatorial wedge). The Alt/Az configuration is considerably more compact than an equatorial mounted configuration, allowing a larger telescope to fit in a smaller enclosure. Unlike German Equatorial mounts, no polar alignment is necessary, there are no meridian flips and no large protruding counterweights to create a potential hazard if the telescope is located in a public observatory.
L-600 Mount Features
PlaneWave L Series AZ Direct Drive
The PlaneWave L-600 features Direct Drive motors and on-axis encoders on both the RA and DEC axes. This eliminates the need for gear-based mechanics, thereby eliminating backlash and periodic error. With the high-resolution encoders providing 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.
PlaneWave L Series mount with CDK mounted ready for high speed slewing for satellite tracking.
The L-series direct drive motors can move the telescope at speeds from 2 degrees and up to 50 degrees per second. This makes the mount ideal for tracking satellites or just minimising celestial target acquisition time.
Dual mounting for PlaneWave L-Series mounts
The PlaneWave 8"-wide dovetail mounting bracket holds telescopes onto the inside of L mounts fork arm. An additional dovetail clamp is available to allow the mounting of an extra supplementary telescope on the outside of the fork arm adding to the mount's versatility.
Azimuth horizontal balancing system
Adding extra accessories to a single-mounted telescope, or adding a second telescope can affect the overal balance of the whole telescope. The upper portion of the L mount can be moved horizontally for precise centre-of-gravity balancing whether the mount is in Alt-Az or Equatorial configuration.
Internal through the mount cabling
To keep cabling from e.g. CCD cameras, filter wheels etc, the L- series mounts feature interior "through-the-mount" cable routing via access panels in the fork arm and azimuth axis sections.
PlaneWave CDK700's at work
The PlaneWave alt-az L-Series uses the same proven technology as used in the well-respected CDK700 telescopes which are being used in Universities such as the UK's University of Central Lancashire Alson Observatory >>HERE<<.
