European Tribune - Comments - Equation of time

Equation of time | 115 comments (115 topical, 0 editorial, 0 hidden)

Does (4) refer to the Moon's parallax or to the 1 degree per day shift in the "star time" due to the Earth's orbit around the sun?

If you're at the same latitude on the same night, there should be no parallax.

Re: Equation of time (none / 1)

Parallax. There is parallax between the position as observed by the almanach-makers and the position as observed by the ship navigator, and that both due to latitude and longitude.

Re: Equation of time (none / 0)

But if you observe at "local midnight" you cancel the longitudinal parallax.
