Dear Alex,
A12 sextant feature an averaging mechanism (manual) but I don't use it. Have you solved the problem of bubble size increasig (from the 10 O'clock position) during observations or did you decide to live with it?

Dear Jean-Philippe,
Thanks for posting them.
They look very good to me, I mean as good as one can probably
hope for, with a bubble sextant. As I understand, A12
does not have an averaging mechanism. Or you simply
do not use it?
My observations seem worse (I have errors of 5' frequently,
but probably this is because of my insufficient experience
with this sextant.
