" ... our first prototype system for the ultimate in portable imaging: a Paramount MX+ on our portable pier, with a battery... okay, nothing new there, right? Well, strapped atop my Veloce was a small plastic box running off the +5V DC power supply on the Versa Plate. This box is a small Linux computer running TheSkyX Pro!
TheSkyX Pro for Linux controls the mount, focuser, camera, and guider, as well as the filter wheel. A secondary LiFePO4 battery provided enough juice for the Starlight Xpress Trius camera and the whole system can run all night on a single charge."
