Dear Friends,

One of the most celebrated quasars is Markarian 205, a fairly bright
quasar in Draco (mag 15.24), which has led to an interesting controversy
the past few years as to whether it is related to NGC 4319 in the
immediate vicinity or not. The dramatic difference between the redshifts
of these two "players" (z=0.07 vs z=0.006) has led to conflicting
interpretations of the redshift and whether it can be used as an
indicator of distance or not.

For an image based on 30 minutes total exposure, I kindly direct you tohttp://www.perseus.gr/Astro-DSO-QSO-Mrk205.htm.

Clear skies!

Dear friends

You have friends? Nice one ... thanks for the laugh!

What I do have is a perspective of one of the great tragedies of
civilisation,the abrupt vandalism of the astronomical discipline by
the gruesome twosome of theorists and guys only interested in
magnification.

The analemma represents that vandalism visited on the Copernican
insight and the great Western adaption where clocks keep in sync with
axial rotation in 24 hours/360 degrees always.

When you get to the Equator where there is always equal amounts of
daylight/darkness through the year,you may even discover that the
Total length of a daily cycle,to which the Equaion of Time is
applied ,has no axial tilt component and has nothing to do with
sunrise/sunsets or variations in the Sun's position longitudinally.

The creation of the equable 24 hour day is an incredible human
achievement,even without the later adaption to clocks,axial rotation
and terrestrial longitudes as a 24 hour/360 degree correlation.That a
civilisation would knowingly choose to vandalise one of the
astronomical jewels which we use day in and day out is incredibly
disappointing,that it also means destroying the ability to appreciate
the Copernican insight for orbital motion touches on an intelectual
and intutive nadir.

Nobody can feel proud of themselves,at least not in this era where the
work of great and careful men remains temporarily destroyed and where
no advancement in future is possible.You want pretty pictures based on
magnification then so be it,the price of that hobby is very,very
expensive .

You're not even wrong.

The great human achievement found in the creation of the 24 hour day
via the Equation of Time correction is by itself an incredibly
enjoyable experience,the heliocentric application of that human
devised which keeps a clock/24 hour day in sync with axial rotation/
terrestrial longitudes makes it an astronomical jewel that truly
belongs to all humanity.

I do not have a monopoly on the explanation of how the average 24 hour
day was overlaid on the daily rotational cycle after the Equation of
Time is applied but I am the first to explain it accurately,at least
in outlines.

As for the analemma and those who follow that junk,well it all goes
back to Flamsteed and that nasty,nasty error of his ,specifically
where he tried to justify the annual and axial motions of the Earth
using the 1461 calendrical cycle -

"... our clocks kept so good a correspondence with the Heavens that I
doubt it not but they would prove the revolutions of the Earth to be
isochronical... " John Flamsteed

Many should recognise the priviledge of being able to set things
right,even the astrophotographer ! .Most certainly people will
eventually wake up to find the great Copernican insights and the clock/
axial rotation correlation frozen in time for one is bound to the
other.

As the orbital motion and the change in the SR/OS boundary must
replace the pseudo-dynamic of variable axial tilt /analemma for
climatological purposes ,I have more of humanities future in mind that
pointing out where guys in the 17th century jumped the tracks or
contemporaries follow them
