Some images are stereo pairs that require looking at the left image with the left eye and the right image with the right eye. Recently I have added cross-view images that require you to look at the image cross-eyed. Others are anaglyphs which require glasses. You will need colored glasses with the red lens over the left eye and the cyan lens over the right eye for anaglyphs. You can order three-D glasses on line. I buy them in bulk. The cardboard ones don’t last long but can be as cheap as $.26 a pair. I have made my own out of different kinds of colored plastic in case you do not have any and want to be creative. I’ve used the colored plastic covers for school reports, camera filters and colored sandwich bags. They do not work well but they are cheap.
A note about the debate between parallel and cross-view viewing. Parallel is easier on my eyes but require the images to be close together and no farther apart (center to center) than the width of your eyes. This limits the size of the image on the device you are using. Cross-view gives me a headache but does not limit the size of the images. In fact, a cross-view pair shown on a big screen in a theater is possible. Since it is able to be enlarged, you can see more detail.
Hubble’s Horsehead
I like to create stereo images of just about anything. Here is the Horsehead Nebula that was taken by Hubble. I created it to look like how I picture it when I look at it. Parallel first, then cross-view with anaglyph last.



More Mars Images in 3D
While waiting for the Moon to wane out of my way (so to speak), I have made a few Perseverance images into 3D. First will be an anaglyph requiring glasses, followed by a stereo pair.
From Oct. 29, 2023.


From October 30, 2023.


A few from 2025.


Cross-view

Images from my talk to the Western Colorado Astronomy Club
I will show an anaglyph first, followed by a stereo pair.
Comet Hale-Bopp
Taken in March, 1997. The first image is an anaglyph, the second is a stereo pair.



Jupiter


Moon


The Lagoon nebula
This is a creation. The stars are fairly accurate as to their relative distances, the imbedded cluster is more of a guess.



The Horsehead Nebula
Another creation of mine.


New Horsehead


The Orion Nebula
This creation I did about 20 years ago.



More of Jupiter


These images from NASA’s Perseverance rover were taken July 9th, 2022. They were rendered into three dimensional images by me to make one composite image. someone on Facebook asked if I was able to do my childhood dream, what would it be. Well, doing things like this for NASA (and getting paid for it too!).
