Soul Nebula Detail as a Sterogram


Parallel Vision

Cross Vision
-
NOTE! This is a personal vision about forms and shapes, based on some known facts and artistic impression. Wieving instructions can be found from a Right hand side menu.
-
Original Image with details can be found HERE.

NEW

Here you can find an Anaglyph, Red/Cyan, Stereo image.
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.

Soul Nebula, testing

SoulAnimation
Animation, Stars vs No Stars.
-
Sometimes it's usefull to see the Nebula without stars.
Human brains has a tendency to form Shapes and lines from a cloud of dots, in this case Stars.
By removing Stars the actual Nebulosity is seen better.
If the object is located in a very dense Starfield, some dimmer parts might not be seen at all.
I have noticed, that large shapes and formations in a Nebula comes visible by this way.
I can compare this to a CT Scan image, where different tissues can be seen. It's still a real image of the human been, even skin and clothes can't be seen.
After all, in a reality, Stars are only mathematical points, with no dimensions, doe the huge distance.
The difraction and atmosphere blow up the image of a Star to a small disk.
The method used for a Star supression is descripted in a "Tone Mapping" PDF-document HERE. An other sample. Working with a dim targets and an extreme dense Star field: http://astroanarchy.blogspot.com/2009/11/power-of-tone-mapping.html

Soul Nebula closeup finalized


After a long, frustrating period, we finally had kind of clear skys!
Actually, I started my imaging session Three times last night and back everything up at between.
Weather was so volatile, since misty clouds from open see are impossible to predict.
-
After all I was able to capture more H-alpha and enough O-III and S-II to build a decent three band narrowband image.
Two versions , as usually, first one in HST-palette and the Second one in "natural colors" mixed from same material as HST-image.
-
Two color chemes,
HST Palette as S-II=Red, H-a=Green and O-III=Blue.
Second image is in natural colors composed from narrowband data. Channels are balanced so, that image match to visible spectrum, H-a + 24%S-II=Red, O-III=Green and O-III + 15%H-alpha=Blue.
-
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations.
Levels, curves and color combine in PS CS3.
-
Telescope, Meade LX200 GPS 12" @ f4.65
Camera, QHY9
Guiding, SXV-AO @ 11Hz
Image Scale, 0,8 arcseconds/pixel
Exposures:
H-alpha 16x1200s Binned 1x1
O-III 3x600s, binned 3x3
S-II 9x600s, binned 3x3
Top of that, some color data from an older wide field image is used.

Wider view to the Soul Nebula. Area of the current image is marked with a frame. -



A Starless version of the Nebula.
I place it here, since it looks kind of nice and the actual Nebulosity can be seen better this way.
