This is another image created from data provided by Deep Sky West as part of my imaging team subscription.
The Veil Nebula is a large supernova remnant in the constellation of Cygnus. This image only shows a portion of the entire nebula complex. The two major strands seen here have the designation of NGC 6960 – upper left corner – which is also commonly called the Western Veil Nebula, and NGC 6974 – shown diagonally from upper left to lower right – which is also commonly called the Central Veil Nebula.
This image was created from data acquired using “narrow band” filters which only allow light in a very narrow spectral range to pass through the filter. In this case the filters used were Hydrogen alpha and Oxygen III filters. The raw data was 18 x 1800 seconds of Hydrogen alpha data and 17 x 1800 seconds of Oxygen III data. The subframes were calibrated, aligned and combined in PixInsight. The Hydrogen alpha and the Oxygen III narrow band data were combined into a color image by using a “HOO” color mapping scheme which assigned the Hydrogen alpha data to red and the Oxygen III data to the green channel and the blue channel. This created a false color image where the Hydrogen alpha data is seen here as red and the Oxygen III data is seen here as blue-green colored strands.
