An experimental 3D-studie, IC 1396 and Sh2-129 in Cepheus

Images are for two different viewing methods, the first is for the Parallel Vision method and the second one for the Cross Vision method. Viewing instructions can be seen HERE.

NOTE! This is a personal vision about forms and shapes, based on some known facts and an artistic impression.

3D-studies of the Veil Nebula supernova remnant

The weather doesn't support the imaging of the new material, so I made a collection of an experimental 3D-studies out of the Veil nebula SNR. Some of the images are new but couple of them are published earlier.

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 known facts and an artistic impression.

A start of the new project, Cepheus mosaic part1

I'm about to make a similar mosaic out of constellation Cepheus, than I made out of constellation Cygnus.
The first part is ready now. It's a four panel mosaic showing two main objects, IC 1396 and the Sharpless 129 (Sh2-129). I managed to get visible an extremely dim planetary nebula candidate, OU4, inside the Sharpless 129.

Cepheus Mosaic part 1, four panels

Note. A largish image, 3MB and 1700 x 1300 pixels

Mapped colors from the emission of ionized elements,

R=Sulfur, G=Hydrogen and B=Oxygen.

At this first part of the Cepheus mosaic, there are four individual panels stitched together. At lower right corner, there is the Sharpless object 129 (Sh2-129). The blueish area, inside Sh2-129, is a recently found plaentary nebula candidate, OU4. The famous astrophotographer, Nicolas Outters, has made this discovery, HERE is a paper about it. OU4 is an extremely dim formation. 11h of O-III light with very fast Canon 200mm EF f1.8 camera lens, was needed to have some hint about it.

I will continue this project, as soon as weather allows. The final mosaic will be 10-14 panels larg
