M57 as an anaglyph Red/Cyan 3D

Original 2D-image and details:
NOTE! This 3D-study is a personal vision about forms and shapes, based on some known facts and an artistic impression.

M57, the "Ring Nebula", project finalized
The halo was clear in H-alpha channel and there was some hints of it in luminance one.
Ring Nebula, M57, NGC 6822, locates in constellation Lyra, near a very bright star Vega. This planetary nebula lays about 2300 light years away from the Earth and has a diameter of 1,3 light years.
The small angular diameter, 230" x 230", makes this target difficult to image. The central white dwarf of planetary nebula nucleus is seen in an image as a Bluish dim star, visual magnitude is 15,75. Star was visible only in O-III channel and luminance channel.

3D-study of NGC 300 galaxy
An experiment with the NGC 300. All the stars from our milky way are removed and the original 2D-galaxy image is the projected to a 3D-surface. The resulting 3D-model is animated to a movie file. The purpose is to show the actual shape of the galaxy, now distorted by a perspective.
Original 2D-image and the technical data:
NGC 300
NGC 300, the spiral galaxy in constellation Sculptor, distance is about 6 million light years.
It's likely, that NGC300 and NGC55 forms a gravitationally bound pair.
I have shot NGC 55, an irregular galaxy, ealier and it can be found here:

Image of NGC 55
"NGC300 and NGC55 forms a gravitationally bound pair."
"NGC300 and NGC55 forms a gravitationally bound pair."
Surface brightness is lowish and this image gave me a hard time when processing the raw data. I tried to keep a "diffused" look of it. Active parts of this galaxy can be seen as a Blue and Red areas in a spiral arms.
A closeup
Technical details:
16" RCOS ja Apogee U9000 camera.
LRGB combo. An Australian remote telescope
5x1200s for the Luminance and 2x600s / RGB-channel . Dark, Bias and Flat calibrated.
Raw data is shared by Petri Kehusmaa and J-P Metsavainio
Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations, added at 50% weight.
Levels, curves and color combine in PS CS3.
Something extra in my image
A bright trail trough a single raw frame of NGC 300.
A closeup, there is odd looking pattern inside of trail.
Mystery was solved by a help from Bert Candusio, the administrator of Northern Galactic group.
Object seen in the image is a geocentric satellite COSMOS 1536.
Thank you Bert.
