The controller is a standard ethernet cable. You could try an ethernet cable long enough.
Whether it would work over the distance is a matter for those who have tried to answer but logically speaking it shouldn't be an issue.
Monitor cable would be dependant on the cameras output (assuming you have a camera to do the remote viewing through). A raspberry Pi or something connected to the camera and streaming the signal via wifi may be the simple answer for monitor cable.

I haven't tested this method but have heard of it. This is a free program, there's paid for systems like StellarMate.
I have a Raspberry Pi 4 so I would go that way but others here sing the praises of the ASI-Air by ZWO, they are expensive, I wouldn't spend that level of money for the same level (or less) of equipment I already have here. Others say Windows mini PC. The much higher priced NUC get mentioned, I have no experience with them and wouldn't spend that amount of money on such a tiny box (I don't have that sort of money to spend).
I'm sure there will be a lot of ZWO fans who love the things and I've also seen mention of members who like the NUC systems.
A little to think about and I'm sure more members will chime in with experiences.
The hand controller cable however is the easy and cheap part.
I can personally check whether a 10 metre Ethernet cable will work with my hand controller, I just need 10 minutes to find the cable and hook it up.
I'll be back (not said with an Austrian accent).
EDIT: A standard Ethernet cable is fine, the hand controller cable is standard Ethernet, I recommend purchasing a decent branded item and personally, I buy a lot of server related gear
and cables through FS.com, their cables are cheap and good quality (but don't buy their cheaper 8 port switch).
