That is definitely a wrong approach. If the mount runs away in Dec it's because the guide pulses are in the wrong direction and need to be reversed. It's fundamental Of course it will guide ok for a few seconds or even longer as long as no pulses are sent to Dec, but as soon as Dec receives any correction pulses, it will send the mount in the wrong direction and every pulse after that just adds to the error until it goes completely off the guide window. This is fundamental, guys!
You are correct, of course.  What was I thinking?
