Sky-Watcher V5 Hand Controller - S30106

Much easier to use than a wi-fi connected tablet, mainly because it has real buttons that you can feel in the dark with your eye at the eyepiece. I had hoped to be able to connect a tablet through the handset so I could use SkySafari or Stellarium to control my AZ-GTI and use the handset keys to make the minor centering adjustments. Had to go back to an old version of Linux Mint (19.3) on a laptop with an older Stellarium (0.18.0) to make the connection. That works perfectly. Have not figured out how to make the connection to the handset from a current Windows, or Android, version of Stellarium though. Still, a great product on its own!
