MDA-TelesCoop Telescope Drive Master with Controller v.2.5 and Encoder

The Telescope Drive Master with Controller v.2.5 and Encoder from Explore Scientific attaches to your equatorial mount and reduces the inherent drive errors while increasing tracking accuracy to as much as 1 arc-second. A mount-specific adapter is required to install it onto your mount, and is sold separately. The Telescope Drive Master (TDM) uses a high-resolution encoder and an electronics package to eliminate the need for Periodic Error Correction (PEC) training. For errors beyond PEC, the TDM allows auto-guider input as well to further increase the tracking accuracy.
