The Great Wall of Cygnus
Due to very cloudy weather I have remade some of my older photos, this time the Cygnus Wall has been remade. This is a combination of several older images from 2008, 2010 and 2014. Two different longer focal length telescope was used, The Meade LX200 GPS 12" and Celestron Edge 11". Beside long focal length images material from shorter focal length optics was used from the Canon EF 200mm f1,8 and Tokina AT-x 300mm f2.8 camera optics. Older material was taken with the QHY9 astro camera and after 2014 Apogee Alta U16 camera was used. Total exposure time is around 30 hours.

Info about imaging technique
I have used my new processing/imaging technique VARES for this new composition (VAriable Resolution Imaging) It's really powerful toolset when data from very different focal lengths are combined to a single high resolution image. The principle is that the high signal/noise elements are from the long focal length instruments and the low signal/noise data from the short focal length optics is used to boost relatively featureless and very dim image elements.

Filaments of Veil in mapped colors
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. A version in visual color palette can be seen here, https://astroanarchy.blogspot.com/2021/09/filaments-of-veil-nebula-snr.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.

INFO
Since all of the heavier elements are born in exploding stars, we all are children of supernovae. Veil Nebula is located in the constellation Cygnus at a distance of 1500 light-years. It spans three degrees of sky, (Moon has an angular diameter of 0,5 degrees at the sky) real diameter is around 70 light-years. I collected data for the photo between 2012-2020 and I made this 3D model in 2021,exposure time is 45 hours

3D-study of Veil Nebula Photo
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.
