Train-n-Track Motor Drive for Vixen Porta Mount Vixen Porta Mount, Porta II Mount
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, 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 unit includes a rechargeable battery with a 110vAC/60Hz adapter/charger. Using a 220vAC/50Hz power source will require a converter (not included).
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.
Installation is easy. You must supply the Vixen Porta Mount.
What is Train-n-Track?
The Train-n-Track (TNT) system 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. In some situations, the altitude motor will run very fast and the azimuth motor will run very slowly. In other areas of the sky, the opposite will be true. Completely computerized alt-az systems will track automatically in any part of the sky. The TNT, however, requires that you adjust the motor speeds for your position.
The adjustment, or training, is very simple. Once you become familiar with the process it can be accomplished in about 30 seconds and tracking will continue for 10 minutes or more without noticeable drifting. At that point you will need to do another simple training adjustment. Quick slewing can be accomplished, without adjusting the tracking speed, by simply pressing one key. This feature allows for re-centering an object without changing the carefully adjusted tracking speed. Manual movement is possible at any time, in both altitude and azimuth, without releasing any clutches.
