There's a good discussion of advantages and disadvantages of the two kinds of sextant horizon mirror at the STARPATH home page: http://www.starpath.com/ In the Celestial Navigation section, subsection Home Study Course, click on Frequently Asked Questions or FAQ's. I much prefer the split-horizon, but my experience over the last twenty years has largely been in measuring lunar distances. My Tables for Clearing the Lunar Distance can be found in the Sight Reduction section of CELESTAIR's catalog: http://www.celestaire.com/catalog/Sight_Reduction/Other_Tables/ Bruce Stark
