"I'm going through all of the derivations of this book because it is only one I've come across explaining the sextant in any analytical detail."Have you also looked at vol. 2 of Chauvenet's "Manual of Spherical and Practical Astronomy"? He derives most of the math that applies to sextants. Simms is much more detailed, but bear in mind that some of the material on "eccentricity" is not right --not mathematically incorrect but mistaken in its assumptions regarding the nature of the possible manufacturing anomalies of sextants.

"If anyone is interested I'll start posting my step by step notes on the derivations."Sounds good. You will find that almost anything that is even marginally on-topic is welcome.
