Filaments of Veil Nebula SNR
I shot most of the lights for this image back in 2016, now I have added some new material to it and reprocessed the whole image. An older mapped color version can be seen here, https://astroanarchy.blogspot.com/2016/12/filaments-of-veil-nebula.html
Photo was shot with a Celestron Edge HD 11" telescope, Astrodon naarrow band filters and Apogee Alta U16 astro camera. New data is shot with a shorter focal length instrument, Tokina AT-x 300mm f2.8 camera lens, same camera and filters. Dim background emission is taken from a new material and added to this photo.
Total exposure time is now 44 hours for the whole three frame mosaic and the resolution is 11.000 x 4000 pixels.

Image is in visual palette from emission of an ionized elements, hydrogen (H-alpha), sulfur (S-II) and oxygen (O-III). Red=Hydrogen + 33% sulfur, Green=oxygen and Blue=oxygen + 33% hydrogen to compensate otherwise missing H-beta emission.

Unveiling the Veiled
Every single pixel in this 3d-animation is from the original 2D-image above. The model is based on on known scientific facts, deduction and some artistic creativity. The result is an appraised simulation of reality. Astronomical photos are showing objects as paintings on a canvas, totally flat. In reality, they are three dimensional forms floating in three dimensional space. The purpose of my 3d-experiments is to show that and Give an idea, how those distant objects might look in reality. More info about my 3D-technique at end of this blog post: https://astroanarchy.blogspot.com/2021/10/unveiling-veiled.html
NOTE. It looks like that the animation has less stars, than the original 2d-image. That's not true, stars is normal photo are getting projected to a same plane. In 3D-model stars are in volume and it only looks like, that there are less stars.
