Cables are a challenge. I wish I could make more wirless, always had intentions of doing that. You can get:
USB -> Bluetooth
Serial -> Bluetooth
Parallel -> Bluetooth
Bluetooth -> Computer
Then all you need is power. And an excuse to spend the money on the above converters
My portable setup is "fully booked" with cables.. the laptop has plugged in 6 USB devices, 1 RS232 and 1 LPT. Makes for a challenge transporting it all in a organised fassion sometimes.
In fact, eyepieces are an afterthought to cables for me. I'm dead if I leave behind a cable, don't really need eyepieces though. The cables take up much more packing space in the car than the few eyepieces too.
Perhaps crazy but it's the way it is.
