Cheers guys, it's taken a while to get here and it's not done yet. There is a lot more to it than I initially thought, but we're getting there. The entry door is not in a good position when the scope is shooting east but I'm hoping to run it all remotely so it won't be as much of a hassle as it has been tonight trying to get the mount aligned. In out / In out constantly tweeking it.
I had to google PHD polar align, I had forgotten how to do it
But here's a phd graph from the em-200 with guiding turned off.
FL is 860mm into the qhy5. Well worth the effort
