PlaneWave Ascension 200HR Mount

The PlaneWave Ascension 200HR German Equatorial Mount is designed to give peerless performance with up to 275 pounds of payload. It uses 360-tooth, 12.1 inch diameter RA and DEC gears, has built-in homing sensors on each axis, and is supplied with a hand pad. The Ascension 200HR is additionally equipped with state-of-the-art high-resolution encoders on each axis that correct for residual mechanical errors including Periodic Error and DEC backlash, thereby enabling long, unguided exposures.
