Content of this Blog
Note, please.
In This Blog, there is lots of experimental material.
To see the actual astro images, please, select a Cathegory, like Nebulae, from a Right hand side menu!
Or You can go to my image portfolio; http://astroanarchy.zenfolio.com/ , thank you.
Huomautus. (Finnish)
Tässä Blogissa on runsaasti kokeilevaa materiaalia.
Nähdäksesi astrokuviani, ole hyvä ja valitse oikeanpuoleisesta valikosta esim. "Nebula" ryhmä. (Kaasusumut)
Tai voit vierailla kuvaportfoliossani; http://astroanarchy.zenfolio.com/ , kiitos.
North Anmerica & Pelican Nebula as an animated 3D.
Please, let the image load for few seconds to see it animated!
One more, 3D-transform from a both halves of the stereo pair, the North America and the Pelican nebula. Stars are removed to better show my vision of a possible 3D-structure.
Original post, 2D-images and details, from this target can be seen HERE.
Other 3D-formats, like anaglyph 3D, Paralle and Cross vison stereo pairs, can be seen HERE.
NOTE! This is a personal vision about forms and shapes, based on some known facts and artistic impression.
The "Cat's Eye" nebula as an animated 3D
I made an animated 3D-presentation from the Cat's Eye nebula too.
Since threre was difficulties with a star field around it, I removed all other stars but the central star of the nebula. The spherical nature of this planetary nebula can be now seen without eye tricks, like in a stereo pair.

Bubble nebula 3D-animation
Sorry, there is some artifacts in image, mainly stars. This is an experimental technique yet.

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!

Stereo pair can be found HERE
An anaglyph Red/Cyan 3D can be found HERE

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.

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.

Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.

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.

Anaglyph Still Motion movies
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.
This was an interesting test. I tested how 3D-anaglyph images might work as a Still Motion movie files.
'They simply work! This will give a new life to 3D-images, it'll kind of adds a "fourth dimension" to images.
I used a Sony Vegas evaluation version to add the Zoom & Pan feature to still images.
How ever, there was a problem with video conversion in YouTube. For some reason it courses chosting in the movie. Original version has no chosting effect at all.
Other samples:

I tested an evaluation version of Sony Vegas video editor to create this effect.
Windows movie maker is a free option to do this, but effects are not parametric, so there is not enough user control for a good result.
This is a good way to show actual resolution of a picture, there is not much point to publish full resolution version of an image due the huge size.

An Anaglyph animation test
I made this funny 3D-video from a Veil Nebula. It shows how it might be formed from a Supernova explosion. Movie is very short though.
