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.
