Designed to attach to popularly available 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.

The electronic controller unit 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, the TDM allows auto-guider input as well.

Most commercial telescope mounts come with a periodic error and other non-periodic error as well. The level of periodic error can be as high as 5 to 40 arc seconds. The TDM will reduce it into about +/- 0.5 arc seconds tracking error that makes imaging very precise.

Scope of delivery

  • TDM - Telescope Drive Master
  • Power Supply
  • Encoder - compatible with most commercial telescope mounts, except the largest ones...

(a different, more heavy-duty version would be necessary for the Paramount ME Millenium edition, all large Fornax mounts (52, 100 and 150) and Meade 16" LX200)

Please note, you'd also have to buy the mount specific adapter for the encoder separately.
