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. For added flexibility, the L-Series mounts can be installed in either Alt/Az, or equatorial mode with the optional wedge accessory.
L-600 Mount Features:
Load capacity of 300 lbs (135 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
