The MGEN autoguider

The MGEN-2 standalone autoguider package consists of a guide camera and a control box. An ST-4 guiding cable leads from the control box to the ST-4 port of the equatorial platform and an RJ45-RJ45 cable connects the guide camera (autoguider) with the control box. The control box and the platform both are connected to a 12V power supply by additional cables.

The MGEN-2 autoguider is designed to also control Canon EOS cameras (exposure time, wait time, mirror lockup time, shots to do). I was fascinated by that feature but unfortunately, for some reason, the autoguider stopped controlling the camera after a few months of heavy use with two different MGEN-2 autoguiders. I tried to exchange cables and the camera but the feature just wouldn't work anymore. Maybe the power supply is the culprit. I now use Gunther Wegner's LRT Pro Timer to control the camera.

Below, you can find images of the MGEN-2 autoguider and its connections and my settings for the control box. No computer is needed for the autoguiding process - one of the biggest advantages over most other autoguiders.
