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.

My last imaging project for this Winter season, a high resolution mosaic image of the Heart Nebula
We are now out of astronomical darkness for about six months due to high latitude, 65N. As every time, it's hard to give up imaging the beauty of the deep sky.
IC 1805, the Heart Nebula is my last imaging project for this season. It's a very high resolution, six panels mosaic image. Image is shot between 20. February and 21. March, total exposure time is 49h. Original size is about 11.000 x 9000 pixels at the scale of one arcsecond/pixel.

INFO
This high resolution photo of the IC 1805, the Heart nebula, is a six panel mosaic. (Original size is about 11.000 x 9000 pixels at the scale of one arcsecond/pixel.) It shows many details in the IC 1805, like the Melotte 15 at the heart of the Heart Nebula. Total exposure time for this narrowband photo is 49h.
The "Heart Nebula", IC 1805 locates about 7500 light years away in constellation Cassiopeia. This is an emission nebula showing glow of ionized elements in a gas cloud and some darker dust lanes.In a very center of the nebula, lays Melotte 15, it contains few very bright stars, nearly 50 times mass of our Sun, and many dim ones. The solar wind, a radiation pressure, from massive stars makes the gas twist to a various shapes.

A small set of image pairs, Wide field vs closeup
I have shot many targets with least two different focal lengths, usually a 200-300mm camera lens and my old Meade LX200 GPS 12" telescope. I have done earlier some scale studies as a zoom in series, with Moon circle as a scale.
Now I have done just simple image pairs, showing both, a wide field and a closeup from the same objects.

Heart and Soul Nebulae, reprocessed
Since the weather up here has been less than supportive for astronomical imaging for a long time, I have played with an older data.
Heart & Soul Nebulae
IC1805 & IC1848
Image is in HST-palette, (HST=Hubble Space Telescope) from the emission of ionized elements,
R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are mixed from the NB channels, Red=H-a, G=O-III and B= 85%O-III + 15%H-a.
My photos, from several years, are used to combine this panoramic image of IC 1805 & 1848.
This emission nebula area is located in constellation Cassiopeia at distance of about 7500 light years.
I have made a scale study to show the apparent scale in the sky, it can be seen here:
Image is in visual spectrum, mixed from the same narrowband material, than image above.

Soul Nebula, IC 1848, as an experimental 3D stereo image pair
The weather doesn't support the imaging of the new material, so I made a new experimental 3D-study out of my photo of the Soul Nebula, IC 1848.
Images are for two different viewing methods, the first set of images is for the Parallel Vision method and the second set for the Cross Vision method. Viewing instructions can be seen HERE.
NOTE! This is a personal vision about forms and shapes, based on some scientific facts, deduction and an artistic impression.

The nebula season is kind of over but up here, 65N, it's still very possible to shoot some nebulae.
The Soul nebula, IC 1848, was in western sky at elevation of 55 degrees when I started imaging, at Nine a clock. I took last images at four in a morning, at that time the elevation was about 30 degrees and it was just past the Northern moust point at a sky. Evem though I spen whole night shooting this, poor transparency, speeding clouds and, due previous, lost guidestar, I was able to use only Seven 20min. frames for this.
Color for the final image are taken from my older narrowband image from 2008, the original Blog post can be found here: http://astroanarchy.blogspot.com/2008/10/heart-soul.html

Who need Stars?
This is a just a test. Large gas clouds are located usually in dense star fields and bright
stars are dominating the image, even in narrowband images.
Sometimes it's difficult to see actual target from stars.
In this test I removed stars from images by using several PS filters, like Minimum, Dust & Scratches and some other star reducing methods.
-
I think, in this way the actual targets and they forms are more visible.

IC1848, the "Soul Nebula", apparent scale in the sky
I have shot many targets with several focal lengths.
Due that, I will publish some of my material as an image sets, with different field of view and detail levels.
The fractal nature of our universe stands out nicely by this way and it will make the orientation more easy.
Many times, it's difficult to understand the image scale of astronomical images.
Due that, I will add a Moon circle in some of the images to show the angular scale in a sky.
The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.

A 3D-study of The Soul nebula detail
This is my new test with a 3d-conversion of my astronomical images. I have published some animated GIF files, this time I have done a short movie out of the model. Even though this is just a looped tip tilt movie, I'm abel to do any movements with this new kind of model.
Only real elements from my image are used, there is nothing added but the volumetric information!
A 3D study of IC 1848
Image is in mapped colors.
Pay attention to a transparent 3d-shapes, they usually are very difficult to animate.
In YouTube you can see this image at a full screen and resolution:
(Click the gear symbol to select 720p )
Info about the technique used
My 3-D experiments are a mixture of science and an artistic impression. I collect distance and other information before I do my 3-D conversion. Usually there are known stars, coursing the ionization, so I can place them at right relative distance. If I know a distance to the nebula, I can fine tune distances of the stars so, that right amount of stars are front and behind of the object.
I use a “rule of thumb” method for stars: brighter is closer, but if a real distance is known, I'm using that. Many 3-D shapes can be figured out just by looking carefully the structures in nebula, such as dark nebulae must be at front of the emission nebulae in order to show up etc...
The general structure of many star forming regions is very same, there is a group of young stars, as an open cluster inside of the nebula. The stellar wind from the stars is then blowing the gas away around the cluster and forming a kind of cavitation – or a hole — around it. The pillar-like formations in the nebula must point to a source of stellar wind, for the same reason.
How accurate the final model is, depends how much I have known and guessed right. The motivation to make those 3-D-studies is just to show, that objects in the images are not like paintings on the canvas but really three dimensional objects floating in the three dimensional space. This generally adds a new dimension to my hobby as an astronomical imager. (Pun intended)

All my new astronomical photos from the Winter season 2014-15
My humble thanks to the supporters, they made my work possible at this Winter season!
First class products and service
This is a collection of my photos from the past Winter season. We are now out of astronomical darkness for about six months due to high latitude, 65N. As every time, it's hard to give up imaging the beauty of the deep sky.
The season was very cloudy too. We had over three months a solid cloud cover this winter and clear nights just now and then. The good side is, that I have been forced to develop new imaging and processing methods to be able to finalise maximum number of photos. The "Tone mapping" method and a new unpublished "VARES" (Variable Resolution imaging method) are very powerful tools for astrophotography. I'll publish the VARES.method in a year or so, after I have tested it well enough.
All of my photos are taken from a light polluted downtown.

One of the most interesting tasks at 2014 was a cooperation with the vocal ensemble Cappella pro Vocale. This cross art production was a mixture of an old vocal music and the astronomical images. The production took place at the church of St Thomas. My photos get projected with three powerful projectors on walls and sealing and everything was matched with the music carefully.
