how do you photo an analemma
analemma
once a week to make the analemma and also have the
blue sky and horizon in the same product at the end of one year?

Then you take an underexposed picture every week,
where only the sun is visible.
then photoshop them into one picture.

I often wonder what the great astronomers did to deserve something as
vapid as photographing the Sun's position using the average 24 hour
day and then trying to explain this wandering analemma Sun using the
Earth's daily and orbital dynamics,I would say such reasoning is the
lowest point imaginable but unfortunately the alternative 'sidereal
time' explanation for planetary dynamics using the circumpolar
rotation of the constellations is much worse if it is possible to be
so.
The idea of a wandering Sun occupying the same arena as the wandering
planets (apparent retrogrades) and both resolved by planetary
dynamics can be set off against the stable principles from antiquity
where the Sun's apparent motion was seen as direct while the planets
wandered over the course of an annual cycle -
"Moreover, we see the other five planets also retrograde at times,
and stationary at either end [of the regression]. And whereas the sun
always advances along its
own direct path, they wander in various ways, straying sometimes to
the south and sometimes to the north; that is why they are called
"planets" [wanderers]. Copernicus
You mean no harm no more than Sam does when he goes bananas over a
sunspot yet all the same,it is hard to see what replaced the great
Western astronomical achievements such as the resolution for the
apparent retrogrades of the other planets using the Earth's orbital
motion while this era allows a wandering analemma Sun,a late 17th
century hoax designed to invert the references for daily and orbital
motions in order to make way for Ra/Dec.

No, the analemma doesn't mean apparent retrogrades, since
photographing the Sun at the same clock time each day will put the
stars in a different position (which, of course, can't be seen when
the Sun is shining).
If the camera took its picture at the same "sidereal time" each day,
there would be no figure 8 with the Sun swinging back.

If you're going to photoshop the image, there's a simpler way:
1. Start with one normal picture
2. Take one underexposed picture with only the Sun visible
3. Photoshop the analemma picture from these two pictures
But if you want to do it the genuine way, you should do a multiple
exposure of one single frame on the film. This requires careful
planning, but it's quite possible to do.
However, in the age of the digital camera: how do you make multiple
exposures on the same image on such a camera? I don't know - there it
may be necessary to take multiple images and then photoshop them into
one single image.

... and your own explanation for this unambiguous result would be...
what?
Quadibloc
His explanation is clear. It's "vapid and meaningless". So
photographing the Sun at regular intervals by the timekeeping average
makes a figure-8 shape. So what? It means nothing, because looking at
things through the timekeeping average is completely upside-down!
So his explanation is that it doesn't need an explanation because
there's nothing worth explaining there. Move along.
How can he possibly expand on that?

It's easy ....
(1) use a mylar filter such as Baader's ND5 which will allow you to
properly expose the sun for the duration of twelve months ... the
foreground will not visible since the ND5 material allows for 1/100000
of the light to pass through
(2) for the foreground from the same shooting location as the
analemma, wait for the sun to clear the field of view and then shoot
the foreground and of course after having removed the mylar filter
material
For many details and tips, check out the fellow who goes by the code
name "oriel" right here on s.a.a. ... aka Gerald.

Paul,
The single-frame challenge is what I did with my ten analemmas and
this only means for this to happen is to use film. My eleventh and
final analemma has been a pain in the butt the past ten years and I
will be starting it again next month. I already have the fresh film
loaded into the camera and I am just waiting for the new year.
If using a digital camera, one would use layers and lighten for the
blend mode to incrementally build the analemma.

An 'analemma' has all the substance in context of astronomy as the
Piltdown man skull has to paleontology but many,many magnitudes more
destructive given that it fostered the emergence of the idea that the
Earth's orbital dynamic can be forced into the calendar based Ra/
Dec.Modelling planetary dynamics and solar system structure directly
by timekeeping averages (Ra/Dec) is far more shocking that trying to
model global climate using a single criteria of a minor atmospheric
gas and if a few scientists rushing to a drastic conclusion can get
120 of the world's leaders to sit down and talk of natural climate
change as a scourge or a human induced disaster then an intelligent
person can gauge how much trouble we are in as a race.
The issue of exploiting the calendar based predictive nature of Ra/
Dec in order to reduce planetary dynamics to an experimental or
modelling level involves the creation of this wandering Sun hoax which
was used in an attempt to invert the references for daily and orbital
motions along with attempting to explain the celestial aberration of
'sidereal time' using planetary dynamics and is central to the
contemporary mess or to be more precise,was the original framework for
this dangerous mess surrounding climate.
Around 400 years ago Galileo paid the price of betraying the Pope by
putting his words in the mouth of a fictional fool insofar as the Pope
was versed enough in astronomical affairs to know that he was being
rolled and the Pope being a political creature threw him to the curia
who knew or cared nothing for intricate astronomical points.Many of
the politicians today now know they have been made to look like fools
by people who cooked the books to get a reckless carbon dioxide/global
temperature conclusion to fly and who now actually undermine the
implementation of pollution level reduction because of this sham so
that our race now ends up in a worse position now than when this
carbon dioxide bandwagon got rolling.No leader is going to allow
themselves to be put in the spotlight like this again based on the
conclusion of scientists,not even if genuine concerns would arise in
future and who could blame them.
At the core of it all is the living nightmare of the analemma and the
'sidereal time' framework which allowed Newton to believe that right
ascension transfers directly into solar system and planetary dynamical
modelling ,I do not expect you to understand this because of you
unintelligent approach to the celestial arena nor many similar who
have similar views to you but like those politicians today,a few would
know that something went badly wrong somewhere and there is no real
authority in existence to handle it.
Anthony Ayiomamitis
Gerald,
Around this time next month I will be going after my eleventh and
final analemma for the tenth time. Hopefully things will pan out this
time so that you will have an extra example to enjoy and savour. ;-)

Who cares,photographing the position of the Sun using the average 24
hour day is a harmless exercise for those who know no better,it is
when it is used to explain planetary dynamics that it joins the
Piltdown man skull as a destructive aberration with particular
emphasis on its origins in the late 17th century as a means to invert
the references for planetary dynamics,even in principle,the idea of a
wandering analemma Sun is so repugnant and lethal to the understanding
of the wandering planets via the Earth's orbital motion that you would
actually need to exist at the level of a flat Earther to make
something of it.
There is a lot of anger and betrayal out there presently on account of
the lack of authority in presenting what actually went wrong with
science but all roads lead back to the attempt to model planetary
dynamics and solar system structure using the calendar based
convenience of the equatorial coordinate system.Like the 'great planet
debate' the Copenhagen conference bears the same directionless end to
it because the conclusion arose out of sanctioned mediocrity based on
these bullies distorting data to fit preconceived conclusions by
ignoring the astronomical inputs as they always have done.
The world exists in unchartered territory at the moment and it is not
such a bad thing,like climate,change is a natural progression and
people adapt as old ideologies are swept away and new ones appear.The
advancement of modern imaging and the ability to make direct
comparisons between planets in our solar system and even other ones
(Fomalhaut) allow more meaningful links to be forged between planetary
dynamics and their terrestrial effects in climate,in geology,biology
or some other discipline and that is why the exposure of empiricism as
a limiting and ultimately destructive tyranny is not the end of the
world.
I do not gloat that I have known all along that the analemma/sidereal
time hoax is the central issue that science faces for the purpose is
not to denounce people as being wrong or crude but to restore a
balanced and stable environment where scientists no longer feel that
they have to support agendas like Newton's and the exotic offshoots of
the early 20th century and approach terrestrial and celestial
phenomena with fresh and modern eyes.Of course,a person who gets
satisfaction from a wandering Sun photography is harmless so go shoot
your analemma as if it were an achievement,the world cannot afford to
pay attention to this empirical creation.

A three-minute egg timer takes about the same amount of time - three
minutes - for the sand to run out of it each time it is turned over.
That is because the flow of sand in it is governed by physical laws.
These physical laws also operate in the heavens. The spectroscope has
proved that, and so has the success of celestial mechanics, based on
Newton's laws of gravity and motion, in describing the movement of the
planets.
You can declaim all you want that we have been fooled by a mistaken
idea, and gone down a wrong path - when we see, time after time, the
proof that this is the _right_ path, the only question is how you can
expect us to heed you.

Today's Astronomy Picture of the Day (December 20, 2009) shows that
you have some competition.
I suppose it must be counted as a good thing that Greece and Turkey
are now engaged in the friendly rivalry of trying to photograph better
analemmas...

Anthony Ayiomamitis
Hi John,
Tunc Tezel and I are friends and we have been exchanging emails for
some time.
As for the particular analemma today and which includes the eclipsed
sun from 2006, it is something that was brought to my attention as
well back in 2004 but the path of totality was 15 hrs away by ferry
(and within Greek territory). Since my analemma work involves
multiexposures on a single frame of film, I would have had to set
things up on the greek isle of Kastelorizo and to have been available
for twelve months for such an exercise. In other words, physically
impossible.
Today's analemma is based on digital exposures (rather than film) and
involves two different geographical locations whose results were later
merged and, hence, for the two names associated with today's APOD.
Anthony.

Make sure you get that guy to acknowledge Copernicus the next time he
takes time lapse footage of the planetary dynamics of the Earth
against the other planets -
http://apod.nasa.gov/apod/ap011220.html
What he has in common with a guy who takes images of a wandering
analemma Sun in the same arena as the 'wandering' planets is anyone's
guess but at least you both know now that there is a lot more to
astronomy than an effeminate exercise is photography.

I can't imagine what goes through your head when you encounter the
leap year of 366 days and then go on explain the annual wandering
analemma Sun cycle using average 24 hours days and the motions of the
Earth but it is probably something similar to the thinking of the guys
who try to '"hide the decline'" -
For someone like me who is capable of dismantling Newton's elaborate
scheme woven around the analemma/sidereal time hoax or to make
something more of Ra/Dec than a calendar based convenience that it
is ,the agenda which tried to force carbon dioxide into dictating
global temperature is childsplay,the machinations and distortions of
the current batch is crude compared to the distortions Newton
introduced and the way he introduced them,after all,it was his agenda
that tried to destroy astronomy.
It is my firm belief that a person who exercises their intelligence in
a productive way will come to realise how little they know and in some
ways that is the way it should be as opposed to continuing on with
contrived reasoning under the tutelage of a pseudo-authority,in
short,it is now easier to say that nobody knows presently what causes
global temperature spikes rather than lunging a reckless conclusion.
Nothing will ever get done and the destruction of science will
continue until the original distortions to astronomy are dealt with
and that means a level of intelligence that can sort out the
distortions which were introduced in order to reduce planetary
dynamics and solar system structure to a human and experimental level
via the predictive Ra/Dec system.

Unfortunately, try as I might, I can't quite imagine why leap years
have anything to do with it.
Yes, the length of a tropical year isn't an exact multiple of the 24
hour day.
The analemma shows two things.
The displacement of the Sun from side to side illustrates the Equation
of Time, the difference between the 24 hour timekeeping average and
the actual natural solar day. You agree that this difference exists.
The vertical apparent motion of the Sun reflects the changing
relationship between the plane of the Earth's orbit, the direction of
Earth's axis of rotation, and the direction from the Sun to the Earth.
The plane of the Earth's orbit, the Ecliptic, doesn't move, and
neither does the Earth's axis, always pointing to Polaris. But the two
of them together define a direction. Since which constellations are
highest at midnight at different times of the year are always
changing, this means that the direction from the Sun to the Earth, in
relation to this defined direction, changes.
Of course, I do realize you disagree with the conventional explanation
of how this relates to the change of seasons.

At least, even if he thinks photography is "effeminate", I can ignore
_that_, and congratulate Anthony Ayiomamitis on having the Astronomy

sun above the Temple of Poseidon.

Thanks John. Glad you like the result.
I will be travelling this coming weekend to scout a 15th century
castle 90 minutes west of Athens for a similar hit over the next few
weeks. I will post results once they are available.
Best wishes for the holidays and the new year!
Anthony.
