My "Cygnus Trio" mosaic was selected as an "Astronomy Picture of the Day" by
the NASA.

The Image

The California Nebula, NGC1499
S-II, H-a and O-III composition, Hubble palette 
H-a+35%S-II, O-III and O-III+30%H-a, "Natural color" composition 
to better show actual nebulosity

This image looks very different, than images of California Nebula usually do.
There is two reasons.
First is, that this is a three color narrowband image, there is not
too many of them, least I haven't seen one.
Second reason is,
that image is "upside down" compared to usual precentation format.
I did this for a reason, narrowband composition reveals new structures in nebula,
they are very three dimensional and this position shows them best.

Imaging data: Camera, QHY8
- Filters, Baader 7nm H-alpha, Baader 8,5nm O-III and Baader 8nm S-II
- Optics, Tokina AT-X 300mm @ f2.8 - Exposures, 5X 1200s H-alpha, 2 X 1200 O-III and 2X1200s S-II + flats and bias
- Guiding, LX200 GPS 12" + PHD-guiding and Lodestar

This is how Claifornia Nebula is usually shown.
Thank You!
Thank you!
Your support is very needed to keep up my observatory, art and publishing work.
All my published images can be found from my portfolio

Cygnus Trio in Stereo pair
Again, this is not a accurate precentation of actual 3D data.
This is more like a "educated guess"
I made this one to show the actual nature of this target.
The gas and stars are floating in three dimensional space forming three dimensional forms,
rather than being a 2D painting on the canvas.

As usual, there is two versions. One for parallel vision, and the other one for cross vision methods. Thats because some part of the viewers can see one of the method in 3D, but not the other. (I can't see cross vision images
-
How to see this in 3D?
Please, look for the right hand side menu for instructions.
Klick this image, if you can't see either of the stereo methods above.
This is a animated image showing steroimage as a small animation.
It will gives an idea, what can be seen in stereo images.
