IMAGE PATCHING ERRORS

Straight line gashes and rectangles blow away some of the center region in Hubble's Ngc 4414.

   

Image patching errors (rectangle straight lines in the midst of coherency) are cited and pointed out systemically throughout Galaxies In Chaos, noticed where an image's integrety breaks down and no further interpretation is possible.

Above, straight lines riddle the center area of a Hubble image of Ngc 3314, the center area has been enhanced, and magnified to the point of almost loosing all resolution except some details are still seen to be coherent in the midst of areas which are clearly only straight edge rectangles of widely variant image densities.

Above, in highlighting in a window a cluster of square patch errors, I also created more rectangle border errors in media densities in this Hubble view of an area in Doradus 30 in the LMC, a simple illustration showing how easy it is for patching errors to actually happen even with great skill and care on the part of pro image engineers trying to avoid bad patches. The point is, most such errors do not turn up in an image until the image is highly enhanced in search of secret details.

When seeing what it can take to collage together an image to get a large wide field view taken in many tiny patches of much smaller field of view, it is understandable how patching errors can occur with such regularity in the most carefully crafted images particularly Hubbles. Here is an example of image collage which was a step in the process of producing final images for a Doradus/Tarantula display.



A 2Mass telescope image of Sculptor Ngc 253 swells to enormous size and becomes exchequered with squares when enhanced by Histogram.



This next example is different, it is a collage made after the fact of factoring individual images.

Two patching errors of noticable strength follow, the first originates here, for the Ngc 1808 globular cluster in the Milky Way.

The second originates here, for the Egg Nebula.

Notice
without wasting
time, that in 3D overlay view
the blue wings both slope away from the
centerpoint into deep space, and both
red flares jet up forward from
behind the centerpoint, a
yin yang crescent
arrangement,
this is
entirely
consistent with the
nature of bi-polar symmetries of nebula.
Also notice without delay that the lower wing's end
point at center is dropped a long way below the center
end point of the upper wing. Such drop is not
particularly seen in nebulas and this
drop in the Egg nebula may be
unusual, for reasons
unknown herein





THE BLUE SMOKE RINGS

Count
the number
of blue smoke rings
seen in the enhancements
and compare the count against
the number of smoke rings seen
in the original. I count five
in the enhanced, two in
the original, this
exploding cigar
is really
smoking

AN INCISING FOOT

Notice
without wasting
time that a major refractive
lensing of some kind is in the form of
a 'foot' around the upper blue wing ovaled
at the hot center point which contains
the nuclear core star causing the
nebula, at first look at the
the foot says it may
be a great
booboo
where a
blue image
was superimposed
imperfectly over a red image,
but on second look, a lense bubble can
be seen at the lower left of center and such a
well formed lens bubble cannot be caused by booboo which
means the 'foot' is well worth a better photo, yet on real close
inspection studying the lens bubble with hard focused steady gaze
in image combining eyesight it can be seen possible that the
lens bubble's edges follow the red edges of image
patching error following the red patch
errors vertically from the
top down. See what
I mean about
needing a better photo

Three pieces
cobbled together at
Hubble for a deep space view
of the Cartwheel ring galaxy and two
nearby small galaxies one containing a star
population of old stars (yellow), and the other
galaxy containing a population of hot new stars
(bright blue). This suggests something - that
these two galaxies contain star populations
separated at birth by a departing
intruder. All of this very
intriguing conjecture
is exposed here



A Dss image of Ngc 6300 holds the record for particle accelator tracks, there may be trackier images in the Dss jukebox but as of this moment in GIC, this holds the record.



Another Dss astronomy error of the day, is Ngc 628, which includes a prominent half clothes hanger in the upper right, two similar coat hangers are also seen in a Dss Bodes galaxy image highly enhanced and seen only at maximum magnification.

Badly
managed or
sloppily presented
astronomy images are almost
non existent on the web. One which
came down from the Dss jukebox seems almost
as if rescued from the refuse bin, certainly it seems
to lack any attempt at professional polish, quite. Here
is what can be done off the top with a quick photo
adjust by 'luminance' in a simple
graphics editor

Another,
of Eta Carinae,
is a prelimary Hubble
black and white, ripples in
the frame seams distort the image.
The image was corrected by computer graphic
programming, changing the image, filling in the
rippled seams with guesswork, which eliminated
some of the most intriguing aspects of
the image

it difficult to tell exactly what is
the Loop, what is error
