Western Veil Nebula

The Western Veil Nebula is a supernova remnant consisting of oxygen, sulfur, and hydrogen gas. This area of Cygnus is densely populated with stars and includes regions of heated gas that make up the Cygnus Loop.

As APOD so eloquently puts it, the Western Veil Nebula is “an expanding cloud born of the death explosion of a massive star”. NGC 6960 (Caldwell 34) is often referred to as the Witch’s Broom as its delicate filamentary structure resembles this memorable shape.

On this page, you will see astrophotography image examples using a DSLR camera, and a one-shot-color astronomy camera using narrowband filters. My latest edition of the Western Veil Nebula was captured from my Bortle Scale Class 6 backyard in Ontario, Canada.

The image above was captured using a monochrome astrophotography camera through a refractor telescope. This image uses the ‘HOO palette’, which means I only used image data collected in h-alpha and OIII.

Video: Photographing the Veil Nebula

The video below takes you through the process of photographing the Veil Nebula, specifically the Western Veil Nebula and Pickering’s Triangle. I used a 430mm refractor telescope (William Optics Zenithstar 73) to capture most of the Cygnus Loop, leaving out the Eastern Veil Nebula. 

To capture this image, a quad-band filter was used to isolate the prominent gases in the nebula. The OPT Triad Ultra filter (2″) was threaded to the field flattener of my telescope and sits in front of the camera sensor. 

The video above features the first time I was able to capture Pickering’s Triangle as well as the Western Veil Nebula in a single frame. The resulting image below should give you a good idea of how wide this area of the sky is (over three times the size of the full Moon!)

The Western Veil Nebula

Capturing the Veil Nebula through astrophotography requires patience and a specific image-processing approach. NGC 6960 resides in a countless sea of stars that must be tamed before the Western Veil Nebula will emerge.

Below, is a wide-field photo of the Western Veil Nebula captured using a DSLR camera and a small refractor telescope. A DSLR camera like the Canon EOS Rebel Xsi used for the shot below is a great way to enjoy deep sky astrophotography through a telescope.

The camera had recently been modded for astrophotography by manually removing the stock IR cut filter above the sensor. This modification certainly helps to record more structure in nebulae such as this, but it is not essential to photograph the Veil Nebula.

Using Narrowband Filters

In August of 2017, I attempted to capture the Western Veil Nebula using Narrowband images from a color camera, the Altair Hypercam 183C.  The image below adds Ha and OIII details to the true color broadband data for a Narrowband/RGB Composite.

The RGB details of this image were captured using a UHC filter (Ultra High Contrast). The Baader UHC-S was effective at reducing much of the unwanted light from my backyard sky, although I prefer the more natural look the Baader Moon and Skyglow (Neodymium) filter creates.

Observing the Western Veil Nebula

This supernova remnant is believed to be produced over 5000 years ago. The Cygnus Loop contains the Eastern Veil Nebula and additional emission nebulosity of the same composition. This is one of my favorite nebulae to observe visually. Under the right conditions, you can follow the tendrils from end to end.

A telescope with a large aperture is needed, and an OIII filter will help. A Dobsonian telescope with at least 8 inches of aperture or more is recommended.

The Western Veil Nebula contains a naked-eye star known as 52 Cygni, which will help you locate the nebula with your telescope.

Below, you will see my photo of the Eastern Veil Nebula nearby. The focal length of my telescope (roughly 600mm) could not fit both objects in the same field of view.

Image Processing

This image of the Western Veil Nebula was photographed from a friend’s house out in the country with darker skies than I am used to from the backyard. The toughest part about processing this image of the Western Veil Nebula was reducing the brightness of the stars that surround the nebula. NGC 6960 is located in a very dense area of the Cygnus constellation.

Because the surface brightness of the Veil is relatively low, you must stretch the data in the nebulosity to create the contrast between it and the starry background. I used the “make stars smaller” action found in Noel Carboni’s Astronomy Tools Action Set, and ran the image through multiple iterations of this command.

It is helpful to mask the nebula while performing this action so you do not lose detail in the object itself.
