Thanks for the advice.
When you do not run them together do you mean seperate conduit?
Cable plan is;
Run 1x usb2 cable to a 4 port hub mounted on pier (1 for ccd, 1 for guider, 1 for gpusb, 1 for focuser).
12V for ccd and mount and maybe for future dew control.
Serial cable for mount control.
Which cables are best NOT to go together?
Thanks
Brett
