This is a composite image. The Luminance data was captured with a QHY5L-ll planetary camera and the colour was captured by a QHY8L OSC camera. The luminance was a stack of 500 frames all stacked in Registax, whilst the colour was a stack of 64 individual images. The moon has very little colour so the colour data is enhanced sinificantly in order to show the subtle hues.
These nebulae are part of a much bigger nebula called the Veila Super Nova Remnant. It is a cloud of heated and ionized gas and dust in Cygnus and constitutes the visible portions of the Cygnus Loop. The source supernova exploded some 5,000 to 8,000 years ago, 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 Dumbbell Nebula known as M27, is a planetary nebula in the constellation Vulpecula at a distance of about 1,360 light years from Earth. This image was taken at a WYAS open night on 2nd September 2013. This was taken using my 8" Celestron U2K SCT scope guided with a Canon 40D DSLR. This image is a stack of the best 26 images taken with a 180sec exposure at ISO 800. This image has an overall combined exposure of 78 minutes approx. Images taken in RAW were stacked using Deep Sky Stacker software to create a composite image with final image processing done in Photoshop CS6 with the aid of B McSorley.
