initial investigation and test video by David Marsh youtu.be/u5ahu5mWM7A
in this video i explain how to analyse the moon's angular speed
@ 7:33 explaining why the moon's velocity is vertically irrelevant to the observed angular speed from earth
@ 10:9 calculate the moon crossing the screen time
@ 17:35 calculate the meridian crossing with up to 4 min error , the error wouldn't have existed if i know certain angle (lunar extreme @ perigee or apogee)
