Thank you for this information about Mr. LaPook, he seams to have quite a bit of information I can hopefully learn from!
I finally pulled the trigger on the A-12 at Celestaire because of the “averaging” tool it includes (you can take an odd number of sights, measured on a bakelite drum with graphite, and from the centerpoint of those sights you can determine the median of the sights with relative ease). A more advanced averager might be nice, but this one has a nice level of simplicity to it. It remains imperfect, but with this type of navigation, the same accuracy of GPS is of course not the goal.
Thank you for the encouragement!
