Default ASTRO: Animation of Crab using Chandra Xray, Radio, Optical and emission line images

There is a neat image of the Crab made using Radio=Red, Optical = Green and
XRAY = Blue he

http://chandra.harvard.edu/photo/200..._opt_radio.jpg

I took the image, rotated it and stretched it to overlay my recently
reported crab shot with emission line filters where [SII] = Red, Ha = Green
and [OIII] = Blue

Once I did that I decided to animate a morphing between the two images. It
is sort of interesting to watch the various structures transform. Some
completely disappear or reappear, while others just transform their color
and or shape.

Warning: this was my first animation. I used Adobe Image Ready. For some
reason it makes the image sort of grainy. Maybe I can figure out how to fix
it. If anyone has some suggestions for addressing the graininess or has
other ideas
of how to do the morphing/animation, please tell me!

here is a link to the file on my website. It is about 2.2MB.

Comments welcome

Clear Skies,

That it is, indeed. I like it!

It is amazing how much the wave-length the shot is taken in changes
everything.

(Makes me wonder just how much such an animation would show if someone were
to take some of the shots of the Crab that go back a few decades, I know that
it is expanding, but wouldn't it be wild to actually *see* it right in front
of you?)

I am glad you guys liked it.

I heard such an animation exists, but I've not seen it. Someone just told me
about it this morning. I understand the data began with an early 1950s shot
from Palomar and it adds data taken afterwards.

Best regards
Richard

I did, I kept it running on my other monitor for a good hour just watching it
while reading the NG on the other monitor. I will go back and grab it again
once Diane gets up, she will want to see it as well.

If you ever found it, let us know, I am sure that I am not the only one who
would be interested in seeing it.

Richard, et al:

That image pretty much knocked my socks off when it was first released!


I took the image, rotated it and stretched it to overlay my recently
reported crab shot.........


That's *really* cool!

I think that the graininess comes from the result being a GIF file. Can
your software produce AVI or MPG? I would bet that either of these would
work better.

I remember seeing b&W photos with a positive with a much later negative
overlaid. Without expansion, the two would have covered each other. But they
didn't and the light areas showed the expansion.

Yes, I remember seeing that.
