PlaneWave Instruments is proud to introduce the Ascension 200 and the Ascension 200HR German Equatorial Mounts. Both mounts are designed to give peerless performance with up to 200 pounds of payload. Both use 360-tooth, 12.1"-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 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 85 pounds. The PlaneWave Instruments Ascension 200 and 200HR mounts are beautifully machined and finished, featuring powder-coated aluminum with stainless steel complements.
