Color CCD Imaging with Luminance Layering

Color CCD imaging poses many unique challenges and frustrations to the astroimager. Despite these difficulties beautifully aesthetic color images are obtainable using a new innovative technique developed by astroimagers
Step by Step Assembly of an LRGB Image using Photoshop 5.5.
Luminance Layering technique can greatly enhance the amateurs ability to successfully produce high quality color CCD astroimages. I hope the above guidelines will help amateurs get started with this new innovative technique.

Are ColorsTrue to Everybody?

Different perceptions of colors as if you could have different ears to listen to music.

  • Normal vision
  • Protanopy
  • Deuteranopy
  • Tritanopy
  • Protanomaly
  • Deuteranomaly
  • Tritanomaly
  • Full colorblindness
  • Atypical monochromatism


Cyndi Lauper "True Colors"


"But I see your true colors
shining through
I see your true colors
and that's why I love you
so don't be afraid to let them show
your true colors
true colors are beautiful
like a rainbow"

ColorSchemer | ColorPix | Galleria | Free

ColorPix is a useful little color picker that grabs the pixel under your mouse and transforms it into a number of different color formats.

You can use the built-in magnifier to zoom in on your screen, click on a color value to copy it directly to the clipboard, and even keep ColorPix on top of all other apps and out of the way.


ColorPix Window with Magnifier

Expanding the ColorPix window to show the magnifier lets you zoom in on your screen underneath your mouse.

You can also control the zoom percentage, up to 2000%.

Blast from the Past 6 | When life was in B&W


The earliest color motion pictures that you will ever see.



Kyle Alvut



"In these newly preserved tests, made in 1922 at the Paragon Studios in Fort Lee, New Jersey, actress Mae Murray appears almost translucent, her flesh a pale white that is reminiscent of perfectly sculpted marble, enhanced with touches of color to her lips, eyes, and hair.
She is joined by actress Hope Hampton modeling costumes from The Light in the Dark (1922), which contained the first commercial use of Two-Color Kodachrome in a feature film.
Ziegfeld Follies actress Mary Eaton and an unidentified woman and child also appear." Thomas Hoehn.

What is Wolfram|Alpha?

 I discovered this tool by Dale Botha !


   Cereously!
"Ceres!  We're going to Ceres!  NASA's Dawn spacecraft is en route and should arrive in February 2015.  Considering we've known about it for over 2 centuries and it is 3 times closer than Saturn and 10 times closer than Neptune and their moons, I've always been very surprised to see the fuzzy images we have of it..."

 About Wolfram|Alpha

"Wolfram|Alpha's long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. We aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything. Our goal is to build on the achievements of science and other systematizations of knowledge to provide a single source that can be relied on by everyone for definitive answers to factual queries..." http://www.wolframalpha.com/about.html

As if the Delaunays had painted an homage to time


"Colhour is a system for visualising time, based on the spectrum of the rainbow. Every variable in the clock - second, minute, hour, day, month and year - cycles through the colors of the spectrum which begins with the color purple. However, the most important aspect is not that all the variables are represented – an application of Colhour could aswell only include the seconds or a combination of a couple of the variables" via harald.net

Sharpen your color sensitivity


 Elvan Online is an online color scheme generator.


"You can either use the RGB sliders or directly the type RGB or HEX values to change the main color. Use "Lighten" and "Darken" buttons to change the lightness. Use "Saturate" and "Desaturate" buttons to change the saturation. You can also choose from different harmony and variation formulas. Adobe Flash Player 6 required to view Elvan Online." Elvan Online

Gamma error in picture scaling


There is an error in most photography scaling algorithms. All software tested (August 2007) had the problem: The Gimp, Adobe Photoshop, CinePaint, Nip2, ImageMagick, GQview, Eye of Gnome, Paint and Krita. Also three different operating systems were used: Linux, Mac OS X and Windows. (Software that don't have the problem are listed at the end of this introduction.)...read this article! 4p8.com

What color is the universe?

The Average Color of the Universe / APOD: 2009 November 1
" What color is the universe? More precisely, if the entire sky were smeared out, what color would the final mix be? This whimsical question came up when trying to determine what stars are commonplace in nearby galaxies. The answer, depicted above, is a conditionally perceived shade of beige. To determine this, astronomers computationally averaged the light emitted by one of the largest sample of galaxies yet analyzed: the 200,000 galaxies of the 2dF survey. The resulting cosmic spectrum has some emission in all parts of the electromagnetic spectrum, but a single perceived composite color. This color has become much less blue over the past 10 billion years, indicating that redder stars are becoming more prevalent. In a contest to better name the color, notable entries included skyvory, univeige, and the winner: cosmic latte. "
