PlaneWave ACENSION 200 HR Mount

Planewave ACENSION 200 HR Montierung

PlaneWave Instruments is proud to introduce the Ascension 200HR German Equatorial Mount. The 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.

The Ascension 200HR is an excellent mount for both permanent observatories and portable applications. Modularity makes the mount easily transportable for field work, breaking down into three components. The heaviest component is 96 pounds.

Kabel durch die Stundenachse

The A200 mount is designed to allow cables to easily run through the mount. At minimum, the two cables for the Declination motor and encoder/home switch should run through the mount. In addition, it is very convenient to run cables for CCD cameras, the EFA kit, and other accessories so that there are no dangling cables that can tangle during operation.
