Soul Nebula, IC 1848, as a two frame mosaic
This image is originally shot this Autumn between 27 and 29.10. I haven't publish it before, since I have had so much material to share. The new imaging system gives me a nice field of view, with a high resolution.
63x63 arc minutes at a scale of 0,95 arc seconds/pixel. That's over a square degree of sky.

Mapped colors from an emission of the ionized elements, Red=Sulfur, Green=Hydrogen and the Blue =Oxygen. The photo is stitched together from two separate shots.

Details of the actual nebula stands out better in this starless view.
Info
Soul Nebula, (Sh2-199, LBN 667) is an emission nebula in constellation Cassiopeia. IC 1848 is a cluster inside Soul Nebula. Distance is about 7.500 light years. This complex is a Eastern neighbor of IC 1805, the "Heart Nebula" and they are often mentioned together as Heart and Soul.
A wider field photo
In this wide field image of mine, the Soul Nebula is shown with its neighbor, the Heart nebula. Image is shot with the Canon EF 200mm f1.8 lens, Baader narrowband filters and the QHY9 cooled astronomical camera. My older photos of the Soul nebula can be seen HERE

Red is a dominant color since the strongest emission line of hydrogen, H-alpha, emits red light. Bluish hues are from ionized oxygen, O-III

NGC 281, the Pac-Man Nebula
A new image from the last week, NGC 281, I spend four nights imaging but the bad seeing and some thin upper clouds ruined majority of my frames. I managed to get enough exposures for two images, the Soul Nebula detail and this shot of Pac-Man Nebula.
NGC 281, in Cassiopeia
Ra 00h 52m 59.3s Dec +56° 37′ 19″
Image is in mapped colors from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Star colors are shot with a QHY8 color camera, Tokina 300mm f2.8 optics and the Baader UHCs filter.
Image is taken at 21. Jan. and there are 23x20min H-alpha light collected for it, color data is borrowed from my older image of the NGC 281. This is the third time for my tandem camera system, Star and natural color of the nebula are shot at the same time, as the closeup image, with the QHY8 color camera and the Baader UHCs-filter. This filter delivers real colors for the stars, even though it's kind of narrowband filter.
INFO
NGC 281 is an H II region in the constellation of Cassiopeia. It includes the open cluster IC 1590 and several Bok globules (dark doo-dads at center of the Blue area). NGC 281 is also known as the Pac-Man Nebula for its resemblance to the video game character from early 80's.
NGC281 spans over 80 light years at its estimated distance of 9500 light years.

This is a link to a 3D-movie, please, have a look:
NGC 281 in visual colors
Image is in visual spectrum and dominated by the red light emitted by ionized Hydrogen, H-alpha. Blueish hues are from ionized Oxygen, O-III. Colors are shot simultaneously with H-a emission by using QHY8 color camera, Tokina AT-X 300mm f2.8 camera lens and Baader UHCs-filter.

A study about the shapes
Lines in the image are showing, how the pillar-like formations are all pointing to the source of solar wind and ionization, the open cluster IC 1590, inside the Pack_man Nebula.
There are some denser material at tip of the pillar like formations and it's able to resist the radiation pressure from the open cluster IC 1590, at the middle of the nebula. Typically those tips are future homes for newly born stars, as well as dark globules seen in the image. The same open cluster is coursing the ionization in Pac-Man Nebula by its radiation. each ionized element in the nebula emits light at the typical wave length.

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)

Soul Nebula detail, IC 1848
I was able to shoot through four nights at last week. Unfortunately three of those night was ruined by a bad seeing, FWHM around 7, and nearly invisible thin clouds ate out the weaker signals. However, I had enough good data for couple of new images, here is the first one, IC 1848.

Heart Nebula collection
I collected my images of the Heart nebula in this blog post. Most of the images are reprocessed with my new method. This new technique will provide better color handling, softer look and high details at the same time.
I have shot many targets with instruments of different focal lengths, this makes possible to show the fractal nature of our universum, more and more details shows up as focal length gets longer.
Be sure to click the images to see them at full glory.

INFO
The "Heart Nebula", IC1805 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.

New imaging project, IC 1848, the Soul Nebula. This season I have worked with a longer focal length instrument, my old Meade LX200 12". This image shows a detail from a much large Nebula complex.
