The Hubble Palette - The effect of Image Processing

The Hubble Palette - The effect of Image Processing

Combining images from narrowband filters is often done using the
Hubble tri-colour palette, in which SII, Ha, and OIII are assigned to
R, G, and B, respectively.

These images show the effect of subsequent processing on images of the
North America Nebula in Cygnus (NGC 7000) taken with a Takahashi Sky
90 with SBIG ST-10MXE. The three images were, in order, unprocessed,
digitally developed using MaxIm DL and digitally developed then
stretched in MaxIm DL.

Better yet is this: HUBBLE SPIES RIBBON IN THE SKY
http://www.abcnews.go.com/Technology...=1&start=false

But it’s all so artificially exaggerated eye-candy, except for our
Selene/moon being entirely monochrome, as meaning without any hint of
mineralogy color or hue worthy saturations.

Hidden Planet/moon mineralogy and shrinkage, and how much has our
Selene/moon shrunk?

Why did some of our NASA teams of prestigious associate wizards
intentionally go out of their way to photoshop and publish this rather
nifty color saturation enhanced image of mercury
(257037main_caloris_color_350.jpg), so as to having selectively
modified its dynamic range in those color saturations in order to
having excluded the thin but hot atmosphere of Mercury, and otherwise
to having removed any possible artifacts of the surrounding background
outside of the planet itself?

It seems entirely odd that their infomercial media has access to
publishing such modified images that are not as such listed within the
official MESSENGER gallery. In other words, we the public are only
getting to see an extremely small fraction of these 100% public funded
image archives related to this mission, such as this color enhanced
image is rather typical.

Too bad we still don’t have the same degree of color saturation
enhanced images of our Selene/moon, as to depicting the complex
mineralogy and better nature of those cosmic deposits on our
physically dark as coal Selene/moon.

An even better color enhanced image of Mercury that’ll show
atmosphere. Don’t be turned off by the extremely pail/pastel or
nearly monochrome first look, because you just have to crank up that
saturation and ever so slightly replace or shift the color of black.
If this is too complex for your expertise, I’ll gladly walk you
through it.

You simply need to have saved this image as is to file, or save it as
a JPG if you’d like, and then PhotoShop it.

PhotoShop: Image Adjust / Replace Color (select: Image)
FUZZINESS: 200
HUE: 0
SATURATION: +100
LIGHTNESS: +5 up to +50 (try using +20)

Next, try out shifting that “HUE” by whatever amount makes you a happy
camper.

By the way; if Mercury has in fact been measurably shrinking by 1.5
km in diameter over its geological history,
http://www.telegraph.co.uk/earth/mai...mercury103.xml
http://news.bbc.co.uk/2/hi/science/nature/7489557.stm

so has Earth been shrinking (though likely by some greater volumetric
proportional amount). I further rest my case from a very old rant I’d
contributed as of many years ago, that pertained to Earth’s shrinkage
from its core cooling as well as from surface erosions (most all of
which ending up in our oceans, displacing water and thus also causing
oceans to rise).

In other words, our Selene/moon may not be moving as quickly as 38 mm/
year away from us, especially if Earth’s radius has been instead
shrinking by several mm/year, not to mention Selene shrinkage.
Another question might be; how large was Earth to begin with?

Venus seems geologically considerably more active than Mercury, thus
Venus shrinkage could also be rather impressive.

I see you were easy to set up again? Feed you the slightest troll and
you pump it into your blog like the good little boy you are, no matter
how meaningless and empty. You have this strange belief that anything
you write in your blog actually makes a difference to the pursuance of
science, and that you opinions weight the matters of fact to your
wants, like a scientologist or something, not a scientist.

AAVSO VSX is one of the poorest and least rigorous reference sources
on the web in terms of actual data validation and confirmation, yet
you quote it as if it was the de rigeur reference commission by the
IAU.

And yet even then, your "new" "variables" that are posted to it are
not deemed publishable by the owners of VSX, even though you keep
nagging them to do so, for after all, there's no other venue you could
publish them in, but this poor bucket hole.

But fact has never bothered you, unless it can be plagiarised without
you being caught.

Incidentally, I see you received no reply from your esteemed vsx
people who's backsides you crawl up. Publish in JAAVSO yourself if
the data is as good as you claim.
