Many thanks guys, for your comments.
Mark, I'm using just the basic non goto black version of the EQ6. All it has to do is track in this game
Thanks for the verification of what Paul said, Trevor.
John, initially I thought my set of Astronomik Type II were not parfocal, but being a newbie & all - That's not true. It was the seeing (bad) that made me arrive at this conclusion. They are *very close* to parfocal in good seeing. I think the B would need a bit of a tweek, if you're pedantic like me with focus
