Alistair,
Here's my quick slew test.
I took an image at a reference position and slewed the scope about 15 degrees away. Then slewed from different directions back to the ref pos and took images.
Most slews returned close. The east and west directions being very good at 8 and 9 arc sec offset.
The north direction gave the greatest error of 175 arc sec but I this was probably down to that I'd not been too fussy setting the Dec worm backlash since the mount was last stripped down and that it's going to be stripped again for further bearing tests.
Cheers, Dave.
