The Train and Track Motor System for Porta II Mount from Vixen motorizes your Porta II mount to make finding and tracking terrestrial and astronomical subjects faster and easier, while reducing image shake. Since closer objects, like the Moon, move faster than deep-space objects, like a galaxy, you can quickly 'train' the speed of the system to track accordingly. Each of the two motors are independently trained allowing for accurate tracking for up to 10 minutes or more without noticeable drifting. If you notice drifting, there are manual slew controls to re-align. This is accomplished without changing tracking settings, so there is no need to 're-train' after slewing. The tension system used in the Porta II mount, means that you can move, adjust, and keep tracking without manipulating locks or clutches, enhancing the accuracy and minimizing vibration and shake.
