| Product Futures |
|
| - Load capacity of 200 lbs (91 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 |
| - Alt/Az, or equatorial installation orientation |
| |
| 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. |

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. |
