Hi John,
only really figured out a way of alining/tilting the focuser from primary
to secondary. Not left to right. I removed the secondary and spider. Sloted
the Chesire in and peered through the sight hole using a ruler I took a
measurement by lining up the sight hole, the crosshairs and the end of a
ruler. Measured the distance to the front end of the tube. Doing this while
holding the ruler inside the tube closest to and over the focuser. Then I took
a measurement on the opposite side and found after a couple of comfirmation
checks that my focuser wasn't square by 3-4mm cant remember now. So
I loosen the bolts on the side that needed to be raised and rolled up a 1mm
or there abouts stick of al-foil and shimmied the focuser. After a couple of
tries I got it close to bang on.
hope this helps
regards
Rob
