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!
Original 2D-image HERE
Other 3D-formats HERE
just few artifacts can be seen.

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!

A Stereo animation
For those who has difficulties to see stereo pairs, there is a clever service in http://www.start3d.com/
It'll turn any stereopair to a smooth animated file.

IC 410 and IC 405 as a Zoomin Movie.
I have shot this area back in 2008 with a 300mm camera lens. In this movie the latest image of IC 410 is embeded in an older wide field image and animated to a still motion movie. By this way, I can show both, wide field and a high resolution in a same image.

IC 410 as a 3D Stereo pair
NEW!
For those who has difficulties to see Stereo images, there is a new service http://www.start3d.com/
This clever service turns Left and Right images, from a stereo pair, to an animated image.
Please, have a look:

Here you can find an Anaglyph, Red/Cyan, Stereo image.
You'll need Red/Cyan Eyeglasses to be able to see images right. Note, if you have a Red and Green filters, you can use them! Red goes to Left eye.

IC 410, a cosmic fertilization
HST-palette
Natural color composition from Narrowband channels.
After many technical and weather problems I managed to get enough data for this image.
IC 410 is a beautiful object next to a "Flaming Star Nebula", IC 405, in Auriga.
Ambient temperature was about -21 celsius degrees and the transparency was good.
Seeing was really bad all night long, about 5 FWHM, so I shot H-alpha frames binned 2x2 to have a image scale of 1,5 arcseconds/pixel.

Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations.

A starless image of the IC 410. This looks now like a Rococo painting, very 3D!

Frustration
I mentioned about hardware problems in this post. Problems I ment are in a telescopes electric, not in my camera. I like to clear this up.
QHY9 will have soon a software update and it'll work without flaws in my extreme conditions too.
Bottom line.
QHY9 has been a bigest upgrade for my equipments ever!
We have now clear up here 65N and temperature is nice -30 celsius (-22 Farenheit).
Seeing looks good, transparency is not too good though.
Can't do any imaging since my equipments are not working due many hardware issues.
I have spend countles hours fixing things and now there is only couple of issues left.
I just have spend six hours to do some power measurements to pinpoint failure(s), three hours of them outside.
I feel really frustrated to be unable to use clear night(s)... what a shame.
NOTE
I made a small face lift to my Blog. There is now larger preview images and both columns are wider, hope you'll like!

Cloudynights forum October 2009 winner
My image of Bubble Nebula was a "Cloudy Nights Imaging and Sketching Contest - CCD Imaging & Processing's" winner.
This post is somehow late, since I noticed this just now.

I have found out, that with this tech. I can combine a high resolution details to a wide field experience.
Seeing the "big picture" helps the orientation and shows the context.
Heart Nebula Zoomout
I made a Zoomout video from a Heart Nebula as well.
Klick HERE to see this in YouTube, please, klick a HD-symbol to see this in HD-format.Movie is made by stitching together a wide field image and a detail image from a same target, in this case the heart (Melotte 15) of the heart nebula.

Bubble Zoomout
Bubble Nebula and a Sh2-157
This video shows the Bubble Nebula in a larger context.Klick HERE to see this in YouTube, please, klick a HD-symbol to see this in HD-format.
Movie is made from two images stiched to gether. Image of the Bubble Nbula is atken with a Meade LX200 12" telescope and a QHY9 astro camera, larger field of view image of Sh2-157 and a Bubble is taken with a Tokina 300mm lens and a QHY8 astro camera.
