MOTODEC is an electric declination motor providing vibration-free, direct-drive declination adjustments
necessary for visual and photographic use. It features a variable speed adjustment for coarse and fine
correction as well as a friction clutch for manual adjustment on some models. Precise positioning is
accomplished through electronic braking. Mounting is easy with no drilling or tapping (except where
noted).
R. A. stands for Right Ascension. A right ascension motor is sometimes called a tracking motor because
it allows a telescope to track the movement of the stars across the night sky, or a clock drive motor
because that movement is measured in clock based hours, minutes and seconds. All of our R. A. motors
have a clutch for manual override.
The Train-n-Track (TNT) system is a basic alt-az motor drive system with adjustable or trainable
tracking. A simple one-minute training procedure allows the scope to track for 10 minutes or more.
The latest option for the GP2 and GPD2 mounts is the new STARBOOK S which incorporates Vixen's legendary
GOTO controller with BUILT IN STAR CHART that shows you exactly where the telescope is pointing and
displays "what's up" right now.
