The PlaneWave Instruments Ascension 200 and the Ascension 200HR German Equatorial Mounts are designed to give peerless performance with up to 275 pounds of payload. Both use 360-tooth, 12.1 inch diameter RA and DEC gears, have built-in homing sensors on each axis, and are supplied with permanent periodic error correction and 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 PE and DEC backlash, thereby enabling long, unguided exposures.
The Ascension 200 and 200HR are excellent mounts 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.
The PlaneWave Instruments Ascension 200 and 200HR mounts are beautifully machined and finished, featuring powder-coated aluminum with stainless steel complements.
