One more test with a 3D-animation of nebulae
not at every time but now and then. After all, this algorithm is originally ment for regular images.
I made a test with a IC 410 nebula image with supressed stars, the actual nebulosity is much more clear and since there is no stars, animation is clean.
Please, let the images load for few seconds to see them!

just few artifacts can be seen.

This service is used to convert a stereo pair images to an animation: http://www.start3d.com/

New 3D animations from deep space objects
You'll find many of them from here: http://astroanarchy.zenfolio.com/f359296072
Due the distance, we can not have enough parallax to create real stereo pairs from deepsky objects.
I have developed, some time ago, a method to add volumetric information to a 2D astro images.
This information is based on some known facts and an artisic impression.
Here are samples of my 3D-visualizations.
This time a special technique is used to turn two slightly different images from a stereo pair to an animation.
Please, let the images load for few seconds to see them!

All animations here are made by using an experimental web service. It'll turn Left and Right images from any stereo pair to a smoothly animated picture. If you'll like to give a try, please, go here: http://www.start3d.com/

Anaglyph 3D astro images and movies
PK 164+31.1, Start of the new project
PK 164+31.1, the "Headphone Nebula"
A false color H-alpha image of PK 164+31.1
I started a new project with this planetary nebula at January 22, the same nigh as I shot the IC 410.
This planetary locates in constellation Lynx. Magnitude is 14 but it has a very low surface brightness. The 16.8 magnitude central star can be barely seen in the image. Distance is about 1600 ly. This is a large object to a planetary nebula, dimensions are 6,7 x6,7 arcminutes. This object is not too commonly imaged.
Seeing was very poor at that night and I shot this target only to see if it can be captured at all. I shot H-alpha frames binned down 2x2, image scale is 1,5 arcseconds/pixel. I'll shoot more frames to this when weather allows and hopefully in better seeing. I have plans to expose O-III and S-II too to make a three band color image out of this target.
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Levels, curves and color combine in PS CS3

Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9
Guiding, SXV-AO @ 8Hz
Image Scale, 1,5 arcseconds/pixel

Exposures:
H-alpha 7x1200s Binned 2x2
This exposure time is way too short for this low surface brightness object!
