Any more posts about astronomy from you and you’ll definitely earn your name.

Learn a little something about spectroscopy and perhaps you’ll see what the Hubble “colors” are all about.

Everything is black and white with CCDs…even your digital camera. The difference is that color filters are ON the chip with your camera (Bayer matrix) and in FRONT of the chip with much of our astronomical images. The HST uses spectral band filters to highlight specific gas emissions, namely hydrogen, oxygen, and sulfur. Both Horizontal Mike and I have such amateur images at our sites using the same technology and techniques. While there is some interpretation to be done – and therefore variance when processing the images – there is a ton of scientific objectivity. Heck, there’s chromatic subjectivity with ALL images, astronomical or not, film or digital, but it doesn’t make them any less important, instructional, or inspirational.

And as for “earthy colors,” we only see what we are designed to see, namely in the 400nm to 650nm range depending on our age and health. Just because you don’t see a spectra doesn’t mean it doesn’t exist anymore than a bear fart doesn’t stink if you aren’t in the woods to smell it.

Sorry to hi-jack the thread, but it really bothers me when people speak out of ignorance to the point where it insults others’ considerable efforts. Shame on guys like us for hoping people would actually appreciate and not insult our work.
