That is not quite correct. I think I have found one of the misunderstandings
in this discussion. Please read carefully.
a) The daily rotation is around the celestial axis.
It produces the nightly star-trails.
We agree on that.
b) The annual orbital translation around the Sun occurs in the ecliptic.
This produces the paralactic ellipses, as I described in pt.5 of this post:
//www.freelists.org/archives/geocentrism/11-2007/msg00917.html
"5) Parallax displays itself as an ellipse with the eccentricity (oblateness)
determined by the ecliptic (not the celestial) latitude of the star. At
the [celestial poles] the paralactic motion over a year, will describe a
circle - at the ecliptic equator a star will go back and forth along
a straight line."
As Paul Deema pointed out in this post:
//www.freelists.org/archives/geocentrism/11-2007/msg00921.html
The [celestial poles] should be changed to 'ecliptic poles'.
This is the annual motion - it is very small scale and will not be
observed by the casual observer.
I believe we agree on that.
c) The crucial part.
What has been interpreted as a separate annual rotation around the
celestial axis is nothing of the sort.
To recapitulate:
i) 1 tropical (Solar) day (24h00m) of the daily rotation puts the
observer in the same orientation with respect to the Sun.
ii) 1 sidereal (stellar) day (23h56m) of the daily rotation puts the
observer in the same orientation with respect to the stars.
Several people have referred to observations in the same direction
w.r.t Earth (e.g., straight up) at local midnight, as showing the
annual motion - see various figures by Allen and Neville.
That is not correct.
It is merely showing different phases of the daily motion.
The true period of the daily rotation, is the sidereal day.
Taking pictures every Solar day merely means that you let the Earth
rotate a bit further (in its daily rotation) before you take a picture.
It's not a separate movement.
Taking pictures every sidereal day will result in the annual paralactic
motion. Again, not detectable by the casual observer.
I hope this helps,
