There are a lot of cameras designed specifically to be used for guiding, and quite a few have an extra "ST4" jack on them to connect to the respective port on the mount for autoguiding.
I had always assumed that meant that the camera was capable of doing the autoguiding on its own, but I had never bothered to play with it since my ASIair+ handled it all. Turns out I am wrong and it's dumber than I was thinking.
