I just started watching this series, and am really enjoying it! You have clearly put a lot of effort and thought into it, thank you so much your generosity!

A couple of tiny remarks: The terms azimuth and altitude (or elevation) are used in astronomy when referring to local topocentric coordinates, whereas right ascension and declination is used for geocentric spherical coordinates. Also, Gerardus Mercator died in 1594, and the slide shows an equirectangular projection, not a Mercator projection. Tiny details that do not detract from the wonderful lecture, but I felt I should mention them :)

What programs do you use for animations?

Sir do you know any website or app for real sidereal time ??
