The Train-N-Track (TNT) system is a basic alt-azimuth motor drive system with adjustable or trainable tracking.  A simple 30-second training procedure allows the scope to track for 10 minutes or more.

The TNT motor drive system includes adjustable speeds on both axes and high speed centering.  The friction drives also allow you to move the telescope around by hand without unlocking any clutches.  You just let go and the drive takes over.  With a little practice, objects can be kept in the eyepiece for 10 minutes or more.  This version of the TNT is battery driven with 8 AA batteries.

The TNT system does not interface with any other products including our MAX guiding computers.  It does not interfere with the MAX computer encoders and hardware.
