Description
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!
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.
