About the Explore Scientific TDM Telescope Drive Master V2.5 Encoder & Electronics Set - Requires Mount Adapter...

Intoducing the Explore Scientific TDM Telescope Drive Master! Designed to attach to popular, modestly-priced equatorial mounts, the Telescope Drive Master (TDM) uses a mount-specific adapter, an ultra-high resolution encoder, and an electronics package that transforms your drive system into a super-performance, research-grade drive. This device does not require tedious PEC training, just turning on the TDM almost eliminates all of the periodic and non-periodic tracking error of your equatorial mount.

 

How Does the TDM Work?

 

The electronic controller unit of the Explore Scientific TDM Telescope Drive Master compares the signals incoming from the high precision rotary encoder mounted onto the RA shaft with the time signal of its quartz oscillator. Any deviations of the angular velocity of the RA shaft from the prescribed drive rate, are compensated by feedback regulation in real time by accelerating or slowing down the drive. If further correction is needed because of errors other than periodic drive error (e.g. dirty bearings, worm gear slipping on its shaft, etc.), the TDM allows auto-guider input as well.

 

Which Mounts Does it Work On?

 

There are adapters which allow the Explore Scientific TDM Telescope Drive Master to fit many popular mounts, including select models from Celestron, Meade, Losmandy, Synta, Orion, Vixen, and Astro Physics.

 

How Much Better Can My Drive Perform?

 

A typical mount can easily have 20-30" (or higher) periodic error as "out-of-box result", Explore Scientific TDM Telescope Drive Master can improve it down to 2-2.5" peak-to-valley total or less, which is often better than the same feature of the very expensive premium category mounts. Certainly, the better quality of mounts will also be able to provide higher accuracy (even less than 1" or 2" total) using Telescope Drive Master.
