3. Universe Today article
s
A new article by Tammy Plotner in Universe Today:
At this time I turned the Hubble Space Telescopes image of "Cat's eye" Nebula
to the spatial format.
-
At the article, there was a comment about error in the original image pair by B. Crumb.
He wrote:
"The axis of the bipolar flow of the planetary nebula doesn't look quite right to me. It doesn't seem to match the velocity measures made of various features within the nebulosity, nor the calculated about 32 degrees to the line of sight. With blunt criticism, Jukka Metsavainio might just like to check a few paper on the morphology of planetary nebula (G.Pascoli work of 1999 comes to mind.), to make sure the stereo images show what has already been derived.Nice pic though."

I have fixed the image pair after the previous comment, thanks B. Crumb.
The Parallel Vision version of fixed Cat's eye Nebula. Hubble Heritage image edited by me.

2. Universe Today article
It looks like Tammy Plotner and I will work together for some time.
Yesterday there was a new article in Universe Today by Tammy.
This time I turned one of the Hubble Heritage images,
MGC281, to a Stereo Pair format.

Distances and shapes in 3D-image are visualizations,
since we don't have enough information to buil an accurate model.
However, the 3D-model of the target is not only
a lucky guess as there is many known "anchor points" in the image,
witch can be used to estimate the actual forms
and the relative distances.

The heart & Soul Nebula as an Stereo Pair.
Ones again, I turned this image of "Heart & Soul" Nebula to a Stereo pair format by adding some volume. The result is more or less an educational guess about real 3D appearance of this formation. - Two versions, first for Parallel Vision , and the second for Cross Vision method.
I made this stereo pair to show the "real" nature of this target. The gas and stars are floating in three dimensional space forming three dimensional forms, rather than being a 2D painting on the canvas.
The "Soul" part of the Nebula (Left) seems to be closer to us
by some sources, some other sources states, that it has a same distance as
the "heart" (Right).
In this Stereo precentation the previous option is realized.

My "Sh2-240" Supernova Remnant image was selected as an "Astronomy Picture of the Day" by the NASA. You can see the NASA page here: http://apod.nasa.gov/apod/ap090131.html

This was my second APOD, previous one can be seen here:
