    Re: Side error and cylinders

    The  Russian SNO-T sextant comes with two little "L" shaped pieces that are used like the cylinders for checking the sextant mirror. See the manual for this sextant that I posted before at:

    This translation calls them "diopters" and their use is explained on page 13 and 14.
