I will likely be crucified for saying so, but I find that a little side
error is a good thing for determining IC using a dim star. It is much easier
to judge when the two images are side by side rather than superimposed.
Perhaps if you try calculating your IC in this manner -- that is, with a
slight bit of side error in your sextant -- your results will improve.

The late Frank Janicek, who was a well-known and well-respected Baltimore
instrument repair man and navigator himself, told me this years ago when I
was fretting about how side error kept mysteriously creeping in and out of
my sextant. I took his advice and have never looked back.
