Could be something I'm doing, but my NEQ6 hooked up to EKOS on an rPi just doesn't seem to be tracking as it should. Everything is working perfectly, however I always use guiding. Which seems to work quite hard, but it's effective. However when I turn guiding off to photograph for example the moon, even though it says that tracking is on, it moves across the frame over the space of a few minutes. The mount is polar aligned through SharpCap to within seconds. This happens even when I have done a plate solve or two earlier in the session.
Would appreciate any guidance, can't think of any other detail I can give.
