The rising feature allows you to adjust the reflected light path compared to the direct light path.
The collimation of the scope directly affects the precision of the measurement.
School me, oh wise ones. The telescope adjustments are not very critical, are they? As long as it's roughly centered on the horizon mirror, Seems as though, perish the thought, a threaded bolt and two locknuts for height and a twist for horiz. and a little non-elastic bending of 'rising piece' bolt would do 'er and actually be pretty solid. The rising piece on my T&S has a bit of play which I can't see how to get rid of, the two #3? screws that adjust vertical (perp to plane of sextant) are quite 'dinky' and given the torque that could be accidentally applied to the longest of my telescopes could damage them.
