The Crab Nebula

No, Stella did not take this one. I received some data for an image of The Crab with a processing tutorial I purchased. I created the image above using part of that data, and posted it on our church website as an example of the beauty and order of God’s heavenly handiwork.

Technical note: Most images of The Crab Nebula utilize data taken through red, green, and blue filters. This is combined during post-processing to produce color images. The data I used for the image above was taken through a narrow-band filter that passes only hydrogen-alpha emissions. I’ve probably already told you more than you want to know, but if you want to know more, just Google “hydrogen-alpha”.

Viewing God’s handiwork in the heavens and pondering the beauty and order of it always leads me to worship the Creator God. (Come on now, we all worship something, so don’t begrudge me my choice of what I will worship!.)

Dave, filled with wonder.

    Thanks for your comment, Jerry. SDG.

    Hydrogen alpha emissions. I’ll take your word on that, and stand in awe of the God who created it! Hmmm… show me what that data looks like sometime.

    It almost looks like a living organism! It reminds me of what a college professor told us one time on why essays are more important than writing fiction: Try describing a platypus – it’s like a challenge from God – describe . Fiction can’t compete, truth is stranger than fiction…

    I think describing your nebula is a similar challenge…

    Thanks for your comment, Tyler. Linda told me it looks like a human brain. Interesting how our imaginations are stimulated by an image.

  6. Leslie says:

    Wow. Linda’s right, it does look like an exposed brain! Tyler, your comments reminded me of acting classes back in the day. I once had to be an amoeba or was it a paramecium…. It was quite a challenge.

  7. Dave says:

    Shouldn’t be a challenge for you! (running and ducking…)
