This continuation develops the equation of time and solar analemma, then connects them to twilight, astrolabes, heliochronometers, and sundials. It shows how astronomical geometry becomes practical timekeeping.

$Live- The Moon In this video, I take a closer look at Live- The Moon using astronomical observations, measurements, and testable predictions. After a very successful live stream of the Sun in Hydrogen Alpha earlier today, I thought I would bring out the refractor for the moon. I want to check polar alignment when it gets dark, but we have the moon for about an hour. Telescope: Orion EON 110mm Refractor Bob the Science Guy | Science You Can Test$
