From this view you can see the camera power and data cables routed back up over the left declination bearing. There is just enough service loop to allow the scope to swing back a little bit past the fork base.
|From this view you can see the guide camera cable and focuser cable routed back over the right declination bearing.|
|This view shows the cables coming over both declination bearings tied down to the fork arms and converging close to the RA bearing.|

|The cables are all tied to the forks just above the RA bearing. They hang from here down to the altitude spreader bar on the wedge. Wire ties are used to keep the cables draping loosely over this bar. The 30cm or so of cable hanging from just a little off-center of the RA bearing produces negligible torque to the drive system.|
|All the cables drop directly into a junction box where they are converted to Ethernet. The only wires going to the pier are an AC power line and a CAT5 Ethernet cable. All the power is distributed in this junction box, from a high quality surge suppressed power module. Long cable runs are avoided to minimize the chance of damage during lightning storms.|
