Default Parallax by Day

Dear group,

Pete Lawrence and I pooled our work from yesterday surrounding the
near-occultation of Regulus by the moon to produce an interesting view
of how Regulus appeared relatively to the moon for the two of us
separated by 2370 km apart.

For an interesting comparison of this apparent view, please see
http://www.perseus.gr/Astro-Lunar-Parallax.htm .... someone please
provide oriel with his medication before he starts mumbling het again
about astrologers, axial rotation, apparent frames of reference and
whatever else I may have missed.

Clear skies!

Anthony.

I'm not sure he actually _understands_ apparent frames of reference. If
he did then he might actually shut up for a while.


Very nice work both of you, by the way :-)

Cool, gentlemen. Exponentially cool.
Praises to the both of you.

Very nice.

I think the inverse picture would also be interesting, with one image
of Regulus and two of the moon. Would the difference in fullness of
the moon be visible?

I thought about this as well ... it can be done and it would probably be
best to have the current moon as is and simply add the second (higher)
moon using Pete's Regulus as reference and with a thin artificial
separator between the two moons.

The Roemerian insight on the astronomical adjustment know as the
Equation of Light is based on orbital comparisons just as Kepler's
refinement of orbital geometries is based on orbital comparisons.

http://books.google.com/books?id=N6T...+jupiter+earth

There is nothing remotely difficult in determining that the illusion
of the irregular motion of Io is due to finite light speed and this is
how the great astronomers understood it .Because the Flamsteed/Newton
maneuver of introducing the astrological framework into heliocentric
reasoning,Bradley finished heliocentricity off by invoking the
background stars and paralax to account for the Roiemerian insight.

The irregular motion of Io still can be seen today and the insight of
Roemer can still be appreciated without appealing to stellar
parallax but rather to orbital comparisons between a moving Earth and
slower orbitally moving Jupiter -

http://homepage.ntlworld.com/heather.../JupiterIo.jpg

http://www.msgc.org/images/ioshadow_msgc.gif

A real astronomer would be taking note of the change in the
orientation of Io's shadow due to the change in orbital positions
between Earth and Jupiter as both planets orbit the central star.

Go back to occultations,personally I think birdwatching photography is
far more difficult than what you do.At least the birdwatchers put
thing in correct context.

Does this mean you will not be computing an estimated distance of the
moon from earth using this collaborative work so that we can compare
estimates?

The image scale of the resampled image is around 2.51"/pixel. ;-)

Astronomers have made use of occultations and specifically using Io
and Jupiter -

http://www.lafterhall.com/io_occulta..._jferreira.jpg

Of course these astronomers worked with orbital comparisons between
Earth and Jupiter in determining the insight that the illusion of the
irregular motion of Io can be explained in terms of finite light
speed.As yuo creeps can't even acknowledge orbital comparisons between
the Earth and the other planets as the main argument for
heliocentricity,you are unlikely to appreciate the Keplerian and
Roemerian refinements of the system

You should be delighted that you are getting a free education,I would
show you where Newton was very naughty in bundling the Keplerian
insight on orbital geometries with the Roemerian insight on finite
light distance but I just find it funny nowadays -

"For to the earth they appear sometimes direct, sometimes stationary,
nay, and sometimes retrograde. But from the sun they are always seen
direct, and to proceed with a motion nearly uniform, that is to say,
a
little swifter in the perihelion and a little slower in the aphelion
distances, so as to maintain an equality in the description of the
areas. This a noted proposition among astronomers, and particularly
demonstrable in Jupiter, from the eclipses of his satellites; by the
help of which eclipses, as we have said, the heliocentric longitudes
of
that planet, and its distances from the sun, are determined." Newton



The nice thing is that modern imaging removes all the garbage of
Newton and exposes the real reasoning behind Copernican reasoning and
even the later refinements.So far you seem to detest astronomy and
what those images are telling you about not only the motions of the
other planets but also the motion of the Earth -

http://antwrp.gsfc.nasa.gov/apod/ima...loop_tezel.jpg

http://www.youtube.com/watch?v=o_fd8O1sk3I

You should enjoy how the faster orbital motion of the Earth accounts
for retrogrades of the outer planets and the faster orbital motion of
the inner planets overtaking the slower Earth accounts for
transits,all bound together in a common heliocentric orbit.

Until you learn that much,you are adhere to the damaging doctrine of
astrology.

Oriel,

I get an estimate of 438,988 km for the distance of the moon from the
earth when, in fact, it was 395,520 km at the time of photography. In
other words, there is an error of approximately 10%.

Clear skies!

Anthony.

Oriel,

I get an estimate of 438,988 km for the distance of the moon from the
earth when, in fact, it was 395,520 km at the time of photography. In
other words, there is an error of approximately 10%.

Clear skies!

Anthony.

I got an estimate of 443,368 km. This is assuming an image scale of
about 3.25"/pixel, which I got from the diameter of the Moon,

557 pixels using the ruler tool in Photoshop CS2
1812" according to http://aa.usno.navy.mil/data/docs/diskmap.html

The distance between the two images of Regulus is 337 pixels = 1096".

Moon distance = (Selsey Athens distance / 2) / tan(1096"/2)

I think the error comes from assuming that the Selsey-Athens base of the
triangle is at right angles to the Earth-Moon vector. In general it
won't be. If tilting that line up to make it perpendicular shortens it
to about 2100 km, we get a very accurate estimate.

You openly mock the methods of astronomers,first the Copernican
insight based on the orbital motion of the Earth,then Kepler's use of
orbital comparisons between Earth and Mars to determine a more refined
orbital geometry and the Romerian Equation of Light insight based on
orbital comparisons between Earth and Jupiter.

The motion of the visble stars of our galaxy around a central axis
will change their orientation to the external galaxies,as you
creatures have the visible stars stuck on an astrological framework
there is no possibility of appreciating this great cycle,even in
principle.The appreciation of Milky Way stellar carousel should be a
matter of course along with the normal perception that the foreground
stars would alter their positions to the external galaxies but this is
the dark ages of astronomy and external galaxies are referenced off
the constellations and its celestial sphere geometry.

Successful people do not do this,men have always had clear geometric
judgements based on physical considerations to create some of the
great achievements of mankind but not this,not this astrological/
magnification exercise .You openly mock uygens treatise on how the 24
hour day is created from variations in the length of the daily cycle
determined at noon or rather the tremedous amount of effort by
civilisation after civilisation to refine the methods that now
constitute the clock/calendar system.

What is it with the English,did John Harrison not put you astrologers
to bed when he invented accurate clocks based on Huygens 24 hour/360
degree principles.The same miserable astrological atmosphere still
prevails not only on account of your stupid correlation between
clocks and axial rotation but the greatest Western astronomical
discovery of all - the Copernican heliocentric system.I well
understand Harrison's frustrations when faced with festering hypocrisy
and it is far worse today.,the difference is that I have the actual
images to show exactly what you lot are- astrologers with telescopes.
