Slashes in dim images or in low resolution regions, may be far away
galaxies seen through obscuring haze. If this interpretation is
correct, there will be a lot of galaxies to be found in dim or dark
background regions of large astronomy images.
Some of the following information is copied from the end of a study
of galaxy M94.
TWO SLIM STREAKS NEED EXPLAINING
In the next image (from this Dss image),
the small slash is at further depth and a different angle its right
end dipping away, whereas the right end of the large slash is angled
sharply toward us in deep space.
Those twin slashes need explaining. Even if nothing but image flaws,
such flaws as this need explaining - what - how. These slashes seem
formed, the larger has a broom tail extending at the upper left end,
and turns away abruptly at the closer near end (at the right).
There seems nothing artificial no thin perfectly straight scrapes no
nose hairs no linen fibres. These are what the slashes are not. What
the bigger seems, is a bi-laterally asymmetric
galaxy seen on edge, a faint show of its strongest radiations glimpsed
through obscuring haze of kind which so dramatically dims M94.
Suspect these are galaxies. Sharp clues are
as follows, seen only in 3D by overlaying the two images together - the
small slash is far distant back in deep space, very far, and the larger
slash has a sharp elbow jog, which is common
in galaxy arms and rims, and cannot be made by some mad astronomer's
razor blades on a film negative or whipping the mouse around on an
image altering computer. In fact the upper broom tail, which bends this
way, has parallel layers, as seen in the low resolution zooms enhanced
above as best as I can get them (see the three 'slash' images above again).
The twin slashes are very large in deep space perspective but not
knowing where they are or what they are rules out that they compare
in size to the optically bright part of M94.
In fact, you might almost think the larger coherental is a sneaky
Dss version of this AAT galaxy but, no
it is not, even though the AAT galaxy (Ngc 3628) has rudimentary
striates in its outer left hidden
dim media flange.
ANOTHER SLASH, IN THE SOMBRERO GALAXY HALO
Another slash has been spotted, in the halo
of the Sombrero galaxy. It may be a galaxy seen on edge through haze. If
not, it definately needs explanation since this is in an ESO image where
image flaw on a negative is impossible since only digital camcord
techniques are used for ESO images.
A subtle circular dimple and other faint different colored irregularities
are where the ESO camera has just barely begun to tap into deep space
rifts, ripples, and cell wall structures (the textures and fabrics of
deep space).
SMALL PAIR OF COLLIDING GALAXIES TURN UP IN HAZE
Is that an hallucination, or is that the 'fish'
colliding galaxies looming through the lower west
hedge of the Sombrero. Notice how the
halo swells beyond the picture frame in this
enhancement showing the very small colliding galaxies. The
Sombrero is giant, much of its bulk mass weak and diffuse, hidden
in dim medias.
It is not the fish, since nothing is seen
nearby in a Dss view good enough to be definative. And of course the
'fish' is a different shape. Whatever the colliders are in the above
'halo mist' view, its name is unknown.
THIN GALAXIES SEEN ON EDGE ARE EASIER TO UNDERSTAND AS SLASHES
This long thinner is in the upper outer halo
of the sombrero galaxy.
Small galaxies of spiral and oval shape salt
the background of a Dss vide field view of the Sombrero galaxy which
teems with far distant objects everywhere. Nowwhere in the Dss view is
the 'slash' or the unnamed colliders seen, not in
strong color tone enhancement either.
Cigar galaxy Ngc 4013 has a dim halo, not
seen in the Hubble original. Two kinds of enhancements - image adjusters,
and Histogram - reveal the existence of the dim halo.
