Dear All,
I follow Don's article and the various instructions and tutorials. I use a combination Cheshire (an Orion). Unfortunately, being very short-sighted I find it hard to accurately align the secondary to centre the primary in the Cheshire and harder still to accurately align the primary as I cannot get good eye placement because of the glasses.
Any ideas? I am thinking of going to a barlowed laser for the alignment of the primary - will this help?
cheers
