Wire Management
That heavy looking wire is actually wire loom, sort of a grooved looking tube that is split along it's entire length. It is very lightweight and effective. I purchased it at a local automotive store and it's inexpensive. In that harness are the 3 wires you see, camera power, USB, & guider. Also in the same tube is the dew (preventer) wire, which I made longer, the Robofocus wire, and the Optec TCF-s wire. Six managed wires. I can slew the SCT anywhere and the harnessed set goes for the ride without imposing any deterrents. One end of the split tube is attached to the SCT grab handle with a Velcro tape thing that I purchased at the auto store. It looks like a roll of tape. One side is fine hook and the other side is fine pile. It is very good stuff. The other end of this harness terminates at the SBIG camera power supply (the black box near the top of the pier). Things just seemed to work well for me this way. Under that box are 2 power strips that plug into the main ground fault protected circuit located just underneath which goes underground to the house. From the power strips come the wires for all things electrical requiring 110V. This includes the Pyramid 20 amp 13.8V power supply. Gemini and the heater get their juice here.
CAUTION: Some people have experienced interference from adjacent wires, especially the CCD USB cable. Dew Heaters are notorious for introducing interference.
Not shown is my laptop computer which is operated from inside the house via Remote Desktop. So that means going to the laptop is a CAT5 cable for the remote operation, plus the power cord, plus a USB cable coming from that white box which is a 4 port USB hub. These wires are also in one of those split tube harnesses. It is amazing the difference wire management has made for me.
Another method is enjoyed by Joe Mize: Radio Shack has Nylon Wire Twists, these are 3/8"-1/2" loops with beads on the ends. Slip the wires inside the loop and twist the beads together one half turn to bundle wires.
