Hi-Res Galaxies - 3D Stereo (DEMO)

[Cimitar (Evan)]

Hi,

By special request, I've applied the 3D STEREO effect to a couple of hi-res galaxy images (M83 and NGC 7331). Please note that I did NOT take these photos. I found Hubble images had too much 'zoom' and they didn't leave enough stars to work with, so I ended up using some images from the ESO in Chile (www.eso.org).

This is my first attempt at applying the effect to a galaxy, my apologies if it's a little rusty (probably good practice though for my up-coming Sculptor image ). I've noticed in my workflow that processing galaxies is slightly different to Nebula, primarily because almost all stars are likely to be in our own galaxy. Therefore they need to sit in front of the target. It seems to work though, as the stars appear to be generating most of the 3D effect.

Hope you enjoy
Cheers, Evan.

CROSS VISION INSTRUCTIONS:
In cross eye freeviewing the image for the left eye is on the right and the image for the right eye is on the left. You stare at a point about 1/2 way to the screen so that your eye's gaze is crossing at the half way point.
As you cross your eyes the image will go double. When your eyes are crossed the correct amount, the middle images will overlap and be in 3D. The two outer images may remain in your peripheral vision and will be in 2D.

Hi Evan,

Again these look great.

Cheers.

Well done. You should make a collection of these. They are fascinating!

While the center of the galaxies aren't accurate you can really get the depth of field with the other galaxies in the background. They way certain lines of gas pop out look great!

Thanks John, much appreciated!

Thanks Adrian, haha, yeah - I've virtually made up my mind to convert all of my images from this point onward. My astro images aren't always the best, but I find with the 3D conversion it provides a real sense of joy - particularly given the fact that I won't be visiting any of these objects in a spaceship any time soon!

I did notice the core of the galaxies didn't work as well as I'd hoped. When I run the sculptor soon I may reverse the images to create a bulge at the core, as opposed to a funnel

Cheers, Evan

I find these fascinating! I especially like the second one (NGC 7331). The effect from our local stars, to the main galaxy, and then to the background galaxies is incredible.
Is there a way to polarise these images so they can be stereo projected onto a screen with the people wearing polarised glasses to view the images without the cross eyed view?
I know with standard terrestrial photography, there are many folk who have a 2 camera setup and stereo projectors to present their masterpieces.

Thanks Bruce , that's a good question. I'm not sure to be honest... but you've got me intrigued so I'll do some research

Cheers, Evan
