RGB and Narrowban data Testing
Original RGB-image from 2007 
RGB + Natural color narrowband data 50%/50% 
RGB + HST-narrowband. Mixed 40% as luminance/60%HST + star color 100% from RGB - -
I found an older RGB-image of Elephant's Trunk Nebula, from year 2007.
It's imaged with a UHC-s filter. this filter gives real Star colors. Camera was a single shot QHY8 cooled astro camera.
Exposures for RGB image:
Meade LX200 Gps 12"@f6.3 with a UHC-s filter, 5x900s only.
-
I have combined this RGB image to a reacently imaged narrowband data.
Interesting looking combination, softer look and real Star colors.

Elephant's Trunk as a Stereogram
For Parallel Vision 
For 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.
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.

The Elephant's Trunk Nebula
In Natural colors In HST-palette - This is a detail from the Nebula IC 1396, a beautiful, sculpture like, gas formation. HERE is a wider field of view to same object. - Technical details: 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 17x1200s Binned 1x1 O-III 4x600s, binned 3x3 S-II 6x600s, binned 3x3
