Interesting test David. Do you think the improved focus at larger spacing is a function of the scope being f6?

I've got my paracorr at 55mm spacing with the qhy8 on my f5 Newt. I focus on a star using a Bahtinov mask then slew to the object I'm after.

Here's how the centre and corners of my image are turning out.
