Elephant's Trunk as a Stereogram

For Parallel Vision For Cross Vision -

LRGB Elephant's Trunk


I had an older version of the Elephant's Trunk from the year 2007.
It was a H-aRGB image.
This is a combination of the olde and the new images.
It can be called to a H-a, O-III and S-II boosted RGB image.

Cat's Eye Nebula

















In Natural Colors and In HST-palette

Uh, this was difficult.
Outer shell is very dim and the core of the Nebula is so bright, balancing that is not an easy task.
I'm happy with this result!
The core of the Cat's Eye Nebula has a small angular diameter, so good seeing is needed to reveal any internal details. I managesd to get some visible by using seceral relatively short exposures, 150s. each, for the core. Seeing varys between 3-2,2 FWHM.
There is a hint of cocentric circles visible around the core, ,they are real phenomen coused by polarized light from the nebula.

Gropped center from the image above.
They are very well seen in Hubble's image of the Cat's Eye Nebula HERE:

A new project, The Cat's Eye Nebula

At the same night, when I finalized the Tulip Nebula, I took first frames for my next target.
Cat's Eye nebula is a small, complex structured, Planetary nebula in constellation Drago.
In this first version, only H-alpha light is exposed. There is strong O-III component in its halo.
Doe its small angular size, good seeing is needed to show any internal details in nebula's core.
Seeing was really bad and I just tryed to capture H-a for outer halo.
However, there was some details in bright core as well.

New project, The Tulip Nebula

I have started a new project with a Sh2-101, the Tulip Nebula.
So far, from three nights, I have only four twenty minutes exposures. Weather has been very volatile up here.
I will shoot more H-alpha and other channels for this object later.

Bubble Nebula finalized













Now I have data for all the channels, H-alpha, S-II and O-III.Even though signal from S-II was very weak it was clearly there, I managed to balance it with stronge channels.

Here is a total captured Field of View, image size is about 3500 x2300 pixels.
Image turned to be a very high resolution one. Image scale is 0.8 arc seconds/pixel.
Seeing wasn't that good (2,5 FWHM at best) but slightly oversampled image is very good for Deconvolution algorithms. After deconvolution the FWHM was 1.9.
