Train and Track Motors for Porta Mount |
| |
The Train-N-Track (TNT) system for the Porta Mount is a basic alt-az motor drive system with adjustable or trainable tracking. With alt-azimuth mounts, the motor speeds will vary greatly depending on what area of the sky you are viewing. 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.
The Porta Mount TNT is battery driven using 8 AA batteries and includes complete instructions. Installing the motors on the Porta Mount is simple. (Porta Sold Separately)
