Mathis Instruments Dual Axis High Resolution Renishaw Encoders for MI-750/1000
Mathis Instruments Dual Axis High Resolution Renishaw Encoders for MI-750/1000 are now available for the MI-750/1000 equatorial fork mounts. Using the Servo II control, a precision encoder rings is installed inside the polar cone and on the fork arm opposite the declination drive. An readhead records the motion of the telescope with sub-arcsecond resolution. Independent of the drive gears and servo motor encoders, the tracking and pointing accuracy to the mount is enhanced using the Renishaw encoders. Tracking errors are reduced to a fraction of an arcsecond, and the pointing errors of the mount are measured in arc seconds over the entire sky.
