Vixen - DD-1 Dual Axis Controller

This dual-axis controller/drive corrector is for use with two optional #3752 Vixen MT-1 motor
drives. These are compatible with the current Vixen Great Polaris, Great Polaris D2, and Great
Polaris Economy German Equatorial Mounts and on telescopes using these mounts. It is also
compatible with the optional MT-1 on older Super Polaris and Super Polaris DX mounts and scopes.

When controlled by the DD-1, the accuracy of the MT-1 motor drive is within +/0.005% of the
sidereal rate. Powered by 8 user supplied D batteries, this will run for approximately 20 hours.
An optional #3599 AC Adaptor is available as is an optional #3828 Manual Operation Clutch,
recommended if manual turning on one or both axis is to be retained.
