    • Greatly decreases drive errors, giving you 1 arc-second capability while allowing you to keep your current mount.
    • Attaches to a variety of available equatorial mounts through a separately purchased mount-specific adapter.
    • Developed to correct tracking imperfections common in all equatorial mounts.
    • Employs an ultra-high resolution encoder with an electronics package that converts your drive system into a research-grade drive with superb performance.

    Explore Scientific TDM Telescope Drive Master Encoder & Electronics Set

    The Explore Scientific Telescope Drive Master (TDM) greatly decreases drive errors, thereby giving you 1 arc-second tracking capability while allowing you to keep your current mount.

    The TDM was conceived by accomplished Hungarian amateur astronomers, Istvan Papp & Attila Madai of MDA Telescoop. They wanted to solve the issue concerning tracking imperfections ubiquitous in all equatorial mounts and the Telescope Drive Master was the outcome. Through the use of a separately available mount-specific adapter, the TDM is made to connect to an assortment of popular equatorial mounts. The TDM employs an ultra-high resolution encoder with an electronics package that converts your drive system into a research-grade drive with superb performance. Tedious PEC training is not necessary. Almost all of the periodic and non-periodic tracking errors of your equatorial mount are removed simply by turning on your Telescope Drive Master.

    The TDM electronic controller unit analyzes incoming signals coming from the high precision rotary encoder mounted to the RA shaft against the time signal of its quartz oscillator. Any RA shaft angular velocity discrepancies from the prescribed drive rate are recouped by feedback regulation in real time through speeding up or slowing down the drive. The TDM also allows auto-guider input in case further correction is necessary due to non-periodic drive errors. In general, a drive on a reasonably priced equatorial mount may have 20-30 arc seconds or more of periodic error by conservative estimates. The TDM will easily reduce this down to 2 to 2.5 arc-seconds peak-to-valley, something you would find with exponentially more expensive equatorial mounts. In many instances that number will experience an even bigger decrease down to 1 arc-second.

    Questions & Answers

    Ask a Question
    • Is there a separately available mount-specific adapter for the Celestron AVX?

      Not at this time. The smallest Celestron mount with TDM adaptation currently is the CGEM/CGEM DX. That mount might be a better consideration for a system like this as the larger mount is stiffer than the VX with a higher capacity, meaning it will benefi

    • Is there a separately available mount-specific adapter for the Celestron AVX?

      I just received notice and a link from optical-systems.co.uk that there is now an AVX adapter, and the web site shows in stock. Does Optcorp have these yet?
