This has probably been addressed before, but I couldn't find anything after a rather cursory search.
I've been playing with Stellarium and it altitude values to practice the math of a sight reduction. I'm assuming I don't have to do any sextant corrections if I use the apparent versus the geometric values for Stellarium's "Alt" generate my Ho? Is the only difference between the two that the apparent incorporates refraction (A2 Tables of the NA)?
Thanks, Dale
