The version 2 of the Telescope Drive Master (TDM) box can overwrite TDM control pulses from the autoguider pulses it can detect through the input connector. The Telescope Drive Master allows the user to select a dim guide star since it manages to keep the RA shaft at strict sidereal measurements or average King rate. If the integration time of your autoguider would have to be one minute long just because there are 15-20 magnitude stars in the FOV of the guiding chip, no problem at all.

The TDM can also help correct air refraction in longer 5-10 minute exposures.

So, TDM with autoguider is ideal symbiosis for creating absolutely perfect images applying extra long exposures. Please note: only LX200 standard output (TDM Out1: RJ-12) can be used simultaneously with autoguider control. SBIG standard TDM output (TDM Out2: SUB D 15) does not relay declination corrections coming from autoguider controller to telescope controller (but RA corrections are transmitted via TDM Out2 as well).

The TDM v2 uses a low correction speed of 0.15x, meaning it can be used when the mount is calm. (0.25x was the minimum correction speed in v1 model.)

Additionally, there are two different types of connectors (for LX200 and SBIG standards) to connect TDM to the telescope driver
