We are changing the design of the polar alignment part of the RST-150H mount. The purpose is to increase the convenience of operation by reflecting the user’s feedback on the usability of the ALT / AZI adjustment part used for polar alignment. The changes made by this improvement are as follows.
Adjustment precision doubles The angle that changes when the adjustment knob is rotated one revolution has been changed Altitude: 2 degrees-> 1 degree Azimuth: 1.14 degrees-> 0.57 degrees
Altitude adjustment part backlash reduced Two additional bearings are used, and machining tolerances of the parts are minimized to significantly reduce backlash.
Increased adjustment convenience The shape of the altitude adjustment knob has been changed, making it easier to adjust without tools. As the bearing is added and the angle per rotation is reduced, a smaller force is required than before. The azimuth adjustment knob has been changed to allow the use of the T wrench provided with the mount.
Increased rigidity of the altitude adjustment part The possibility of breakage when operating with excessive force has been reduced.
