Two questions please. 1. If using equal altitudes over a lengthy period of time, wouldn't one have to account for changes in declination? I don't see that. Perhaps it is buried in the math? 2. The author speaks of "culmination" not occurring at the meridian transit for the Sun, moon, or planets. Would someone please expound on why? Thanks
