The Veil Nebula is the remnant of a supernova explosion that occurred thousands of years ago. At its peak, the "new star" could have been as bright as the crescent Moon but it soon faded to become invisible to human vision. Discovered by William Herschel in 1784, the Veil Nebula is the expanding cloud of the gases of the exploded star, plowing through space and exciting interstellar atoms to glow with characteristic light - red for atomic hydrogen and blue-green for oxygen.
The distance to this object is not accurately known but has been calculated to be about 2,000 light years away.
The Veil nebula is an extended object and consists of different parts, each catalogued with a different name. This image was shot with a small refractor telescope and a DSLR camera and depicts the eastern part of the Veil, which is often referred to as the Network nebula. For an image of the western part of the Veil (NGC 6960), see: www.flickr.com/photos/georgebok/49715381951/in/dateposted...

Portion of the Eastern Veil Nebula also known as Caldwell 33, whose brightest area is NGC6992.
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.
The Nebula was discovered on 1784 by William Herschel.
Given a distance of 2400 Light Years, this gives the radius of the entire nebula as 64 Light Years.
Undulations in the surface of the shell lead to multiple filamentary images, which appear to be intertwined.

Eastern Veil Nebula (C33)
I've recently upgraded my astro setup with a new scope (Takahashi FSQ-85EDX Baby Q) and also had several clear nights to try it out (amazing as new gear normally comes with clouds). I've also been learning AstroPixelProcessor for stacking and processing which has made a big difference to the final results.
The Eastern Veil nebula (designated parts IC1340, NGC6992 and NGC6995) is part of the larger Cygnus loop - a supernova remnant about 1500 light years away in the Cygnus (Swan) constellation and is 5000-8000 years old. The total size of the nebula is about 3 times the width of the full moon.

Well after re-processing the Western Veil nebular from 2018 data and the fact the weather is wet and cloudy I thought I would also have a go at the Eastern Veil from 2018.
Like the Western Veil this is also rich in Oiii so I combined the starless Ha with the Oiii using blending mode lighten in PS to created the luminance layer. Once I have processed the luminance I added the stars back.
Object Description:-
NGC 6992 the Eastern Veil Nebula is in the constellation of Cygnus at a distance of approximate 1,470 ly with a visual mag of 7.0. This is part of a larger structure and is the remnant of a Supernova which is believed to have taken place between 3000 and 6000BC. The whole object (of which this is only part) covers an area of equivalent to 6 times the Dia of the Full Moon. This object is very rich in Oxygen (Oiii)

The Eastern Veil nebula is a cloud of heated and ionized gas and dust in the constellation of Cygnus, located at around 1470 light-years from Earth. It is part of the Cygnus Loop which is a 7000 years old, faint supernova remnant, covering roughly 3° on the sky (almost 6 full moons). The red hues in this image are from ionized hydrogen gas clouds, emitting light in the H-alpha wavelength, while the cyan hues are from oxygen ions.

This is the Eastern Vail Nebula, made up by NGC6995 (left) and NGC6992 (right). Along with the Western Vail Nebula and Pickering's Triangle, they form the Cygnus loop in the Cygnus constellation. The Eastern Vail Nebula was once a star about 20 times the size of our Sun that went supernova 10-20 thousand years ago. The filament like structure of ionized gas and dust span approximately 130 light years and is 2400 light years away from Earth. This is a bicolor image using Ha and OIII filters due to the strong emission of ionized Oxygen (Blue/Teal) and Hydrogen (Red) molecules. The total exposure was 7 hours split from data taken in April from Bortle 2 skies in Texas and September from my backyard. This is one of my favorite images to date! More to come!🔭

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus, at about 2400 light years from us.
It constitutes the visible portions of the Cygnus Loop,a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. In modern usage, the names Veil Nebula, Cirrus Nebula, and Filamentary Nebula generally refer to all the visible structure of the remnant, or even to the entire loop itself. The structure is so large that several NGC numbers were assigned to various arcs of the nebula. There are three main visual components: 1. The Western Veil (also known as Caldwell 34), consisting of NGC 6960 (the "Witch's Broom", Lacework Nebula, "Filamentary Nebula"; 2. The Eastern Veil (also known as Caldwell 33), whose brightest area is NGC 6992, trailing off farther south into NGC 6995 (together with NGC 6992 also known as "Network Nebula"; 3. Pickering's Triangle (or Pickering's Triangular Wisp), brightest at the north central edge of the loop, but visible in photographs continuing toward the central area of the loop.
The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. At the time of the explosion, the supernova would have appeared brighter than Venus in the sky, and visible in the daytime. The remnants have since expanded to cover an area of the sky roughly 36 times the area of the full Moon.

The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop (radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded circa 3,000 BC to 6,000 BC, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light-years.
The Hubble Space Telescope captured several images of the nebula. The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen. This is also one of the largest, brightest features in the x-ray sky.

Finalmente era giunto il momento di dedicarmi alla famosa ed interessante Nebulosa Velo, chimata anche Cygnus Loop, Nebulosa Cirri e nebulosa Filamentaria. E' ciò che rimane dell'esplosione di una supernova avvenuta crca 10.000-20.000 anni fa.
Questa nebulosa diffusa, tuttora in espansione, ricchissima di Ha, OIII e S è molto vasta e per fotografarla nel suo insieme occorrono corte focali, ma focali più lunghe permettono di evienziarne gli intrecci e filamenti che la compongono anche se si è costretti ad inquadrarne solo una parte.
L'avevo già fotografata nel 2014 (flic.kr/p/oU4mqe) e nel 2024 (flic.kr/p/2q9HMCi) con il teleobiettivo Zenit Jupiter 11-A focale 135mm; in questa occasione ho fotografato con focale 420mm la parte orientale, alla quale sono state assegnate le sigle NGC6992, NGC6995 e IC1340.
Grazie alla sua luminosità l'elaborazione non è stata molto laboriosa anche se non è stato facile evidenziare anche le parti molto evanescenti.
Questo appagante risultato lo voglio dedicare a mio padre, che è venuto a mancare il 18 agosto scorso. Lui non era attratto da questo mio hobby, ma mi piace pensare e sperare che da lassù adesso possa godersi questo spettacolo dell'universo. Ciao papà!
________
The time had finally come to dedicate myself to the famous and interesting Veil Nebula, also called Cygnus Loop, Cirrus Nebula and Filamentary Nebula. It is what remains of a supernova explosion that occurred approximately 10,000-20,000 years ago.
This diffuse nebula, still expanding, rich in Ha, OIII, and S nebulae, is very large and requires short focal lengths to photograph it as a whole, but longer focal lengths allow you to highlight the interweavings and filaments that compose it even if you are forced to frame only a portion.
I had already photographed it in 2014 (flic.kr/p/oU4mqe) and in 2024 (flic.kr/p/2q9HMCi) with the Zenit Jupiter 11-A telephoto lens with a focal length of 135mm; On this occasion, I photographed the eastern portion with a 420mm focal length, which was assigned the designations NGC6992, NGC6995 and IC1340.
Thanks to its brightness, processing wasn't very laborious, although it wasn't easy to highlight even the very faint parts.
I want to dedicate this satisfying result to my father, who passed away on August 18th. He wasn't drawn to this hobby of mine, but I like to think and hope that from up there he can now enjoy this spectacle of the universe. Goodbye, Dad!

La nebulosa del Velo es una nube de gas caliente e ionizado.
Es la parte visible del Bucle de Cygnus. Es una nebulosa muy extensa y se suele dividir en tres grandes áreas: El velo Oriental: (Caldwell 34) que se halla cerca de la estrella 52 Cygni. El velo occidental (Caldwell 33), y el Triángulo de Pickering Wisp. Se trata del remanente de una supernova relativamente débil en la constelación del Cisne.
La supernova que le dio origen explotó entre 5000 y 8000 años atrás, y los restos se han expandido desde entonces para cubrir un área de aproximadamente 3x3 grados, cerca de 6 veces el diámetro de la luna llena. La distancia a la nebulosa no se conoce con precisión, pero el Far Ultraviolet Spectroscopic Explorer (FUSE) estima la misma en unos 1470 años luz.
ngc6992, the Eastern Veil nebula and the cygnus loops!
I'm aware of not being as original choice of subject in this case, but I had a mediocre shooting of this object did years ago, and I wanted to photograph it again, but better!
that's about 28 shots @1600 iso with a Canon 600D full spectrum and 80/480mm super-apo triplet reduced 0.8x, about 1h 25min total integration time, not so much but enought for the dark sky of Colle di Sampeyre, italian western Alps :)

About The Cygnus Loop
Containing many components such as The Eastern & Western Veil Nebulae NGC6960, NGC6992, NGC6995, IC1340, Pickerings Triangle, NGC6974 and NGC6979. Cygnus Loop is a supernova remnant, the expanding cloud of diverse elements created in the most powerful of explosions; a supernova.
As a Massive star nears the end of its life, it runs out of hydrogen fuel and begins fusing helium. After exhausting its supply of helium it begins to fuse heavier elements until finally, the star's core can no longer exert enough outward pressure and it collapses. A shock wave rebounds through the star so fierce that the star is shredded and leaves behind a small but extremely dense body; either a neutron star or a black hole.
The progenitor of this supernova remnant exploded more than 5,000 years ago and over the course of the past 5 millennia, the material has been racing away in all directions. The Cygnus loop now occupies a vast region of sky, equal to 36 full moons!
A Supernova seeds the interstellar medium with all types of heavy elements. In fact, every single atom of elements heavier than iron was created in this type of event, including many in your own body.

The Veil Nebula captured recently using the new QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on the Takahashi 130 FSQ that we have the honor of testing for QHYCCD.
In this Hubble Palette version (SHO) the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. while the colors in this image are not the true colors, the narrowband filters used in the making of this Hubble Palette image reveal much more of the hidden gasses not visible in a broadband image, covering an area over 3 x 2 degrees of sky of are the Eastern Veil Nebula NGC6992 to the Western Veil Nebula NGC6960 (Witch’s Broom) far right with “Pickering’s Triangle” in between at the top of the image as well as “The Funnel” just below and the many knot’s and strands visible here and within this beautiful Supernova remnant.
