My brother Don took possession of the 10" Super Deluxe version from Andrew's just yesterday, and due to work commitments I haven't had time to do a full collimation on it right from basics, nor had the chance to look at a star.
However from a
quick check yesterday afternoon with a combination Sighting/Cheshire tube the secondary position looks pretty well right, and a spot test with my laser collimator gave me a red dot on the inner edge of the primary's centre ring, and a return target dot positioned approx 5 mm off dead centre. A minute later both were dead on of course.
Not bad considering it was sold by a "carton dispenser" and then travelled a thousand km's or so via truck!
