An inquiry to you inveterate tinkerers and modifiers of telescope equipment: In the field, the portable power supply for my go-to telescope contains a 12-volt battery and connects to the scope with a thin double wire. The wire's 25-foot length is ample to accommodate the scope's movements, but I sometimes trip over it in the dark and, as the scope slews and pans around in the azimuth, the wire winds awkwardly about the tripod legs. Where could I find some presumably spring-driven device that will hold the wire, play it out and retract it smoothly, like they have for laundry lines?
