Explore Scientific TDM Ver. 2.5 Encoder & Electronics Set
Explore Scientific's Telescope Drive Master features an impressive 1 arc-second tracking ability by drastically reducing drive imperfections so you will not need to give up your existing mount. This makes the Explore Scientific Telescope Drive Master a crucial accessory to have!
The vision of accomplished Hungarian amateur astronomers, Istvan Papp and Attila Madai of MDA-Telescoop, the Telescope Drive Master (TDM) is the result of their desire to solve the issue of tracking imperfections that, to some degree, are inherent in all equatorial mounts. The TDM is designed to attach to a variety of popular equatorial mounts via the use of a separately available mount-specific adapter. An ultra-high resolution encoder and electronics package are used by this Telescope Drive Master™ to convert your drive system into a superb research-grade drive offering superior performance. Tedious PEC training is not required for this device. Simply turning the TDM on eliminates close to all of your equatorial mount's periodic and non-periodic tracking errors.
Incoming signals from the high precision rotary encoder mounted to the RA shaft, are compared with the time signal of the TDM electronic controller unit's quartz oscillator. Any fluctuations in the angular velocity of the RA shaft from the required drive rate are offset in real time by speeding up or slowing down the drive via feedback regulation. If further correction is necessary due to other errors, the TDM also allows autoguider input. An ordinary drive on a reasonably priced equatorial mount can have 20-30 arc-seconds or more of periodic error easy. With the TDM, you can comfortably reduce this down to 2-2.5 arc-seconds peak-to-valley, a level you would expect to enjoy only from equatorial mounts that cost several thousands of dollars. In many instances, that number will drop even more to 1 arc-second.
Requires mount specific adapter.
