Jims Mobile (JMI) TNT Train-N-Track for Meade LightBridge Telescope
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.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 and one-touch re-positioning of the altitude tangent arm. (Current data indicates that the TNT slews the LightBridge 12 at about 7x to 8x.) The azimuth friction drive also allows 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 an AC adapter/charger.Installation requires drilling nine small mounting holes (for #4 screws) in the rocker box. You must supply the LightBridge telescope. Drop-in brackets make removal and re-installation short and simple.
