That's exactly what I do:-) And this is a nuisance. � > My problem is that I cannot do that adjustment using my SNO-T sextant. > am short sighted about minus 8 dioptres nowadays and it isn't > possible to shorten the Galilean scope I also have an SNO-T, but I am far-sighted. Do you have the Kepler (=day, Sun inverting) scope standard for SNO-T ? I always use THAT scope. It seems to me so far superior to the Galileo SNO-T and to all other Galileo scopes, and actually to all other scopes I ever tried that I always use it, except in the cases (form a small boat when there are waves, when I use no scope at all. I suppose that it permits adjustment for any kind of eyes, though I cannot try, because I have only one set of eyes. Alex.
