3D Bubble Nebula
Parallel Vision
Cross vision
The Bubble nebula was a very firs target I shooted with the SXV-AO, active optics unit.
There is info about original image in the archives.
This time I added some three dimensional effect to it. (don this ealier, but with differen
tecnique) The Bubble is odd looking object. It has diameter about six miljon light years!
It's really a hollow space inside Red hydrogen, emptyed by a massive star
by pressure of a solar wind.
There is some viewing instructions in ealier posts.

M81, 3D transformation
This is example image of three dimensional transformation.Original 2D image of M81 is now turned to freely rotatable object.
Pretty far from actual astro photography, umh...
Interesting tough.
M81, Odd Stereo Pair
Parallel vision
Cross Vision
As you can see, this stereo image looks litlebit odd, since you can not see this galaxy from this
angle anywhere from Earth! Explanation in previous post.
M81 experiment
This image pair is not a stereo one.On the Left image, M81 galaxy is as we see it from our home planet.
On the Right image, M81 is seen from directly above!
I was doing stereo pair from Glaxy M81 and I needed to correct the galaxy to "flat"
(perspective correction)
The shape of the galaxy is more visible by that way, I think. Anyhow funny looking
transform.
I can now make a grayscale hight map out of this corrected image.
When corrected bitmap is projected back to the 3D surface, I have a model of galaxy.
Now it's possible to freely rotate the object and selext any vantage point to observe.
