Thanks Malcolm, I'll try that routine, using Darv in place of PHD.

Just to clear, I am no expert, dobs are more my thing but I am having fun learning all about these EQ beasties.

I've been using EQ mounts for 57 yrs, but am not handling the
digital/electronic/ computer age at all well.

I wonder if the problem lies in doing a 2-star rather than a 3-star alignment? A 3-star also accounts for cone error, so if you do have any significant cone error a 2-star will give poor results.

Hi Ken, I am well aware of cone error, and check mine regularly, as I think my 8" f/5 plus extras is close to the limit the vixen size dovetail bar can handle without a bit of distortion. I do find I have to make minor adjustments each time I check it. I will however do a 3 star, and see if it helps.
