Using direct guide is nothing Paul. You simply set it to direct guide in the autoguiding tab in CCDsoft. That's it. If you are using some other software then I am not sure. Its not a big deal. It gets rid of the autoguider USB cable so its one less cable. I have read it is better but haven't done any testing to know if that's true or not. It sounds like its more direct so anything that gets rid of a via is going to be better generally speaking.
