That, Allen, was a very clear and to the point post. Thank you. I agree that your two figures and your explanation of them, are consistent with HC. A slight clarification, though; In HC the period of Earth's daily rotation is the sidereal (stellar) day of 23h56m, which means that the rotation of the camera (around the celestial axis) in the right drawing, is due to the daily rotation. - Regner - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Quoting j a <ja_777_aj@xxxxxxxxx>: > Allen, > > Here is a new drawing for your consideration.
