About this image
Jay McNeil once again here with this amazing image of the nebulae in the area around Deneb in Cygnus.
Deneb, the brightest star in the constellation of Cygnus, the swan, is the bright blue star (at upper right) in this image. The image covers an area of sky equivalent to more than 200 full moons. The deep red glow from Hydrogen-alpha emission lies at the far end of the visual spectrum. Jay's camera converts roughly 60% of the signal that falls upon it to usable data in this part of the spectrum. The vast majority of detail seen in this image is also extraordinarily faint. Even peering through the largest visual telescopes in the world would not help to reveal the ruddy structure captured by the camera in the image. An exposure of more than 11 hours was needed and the honey-like glow towards the center of the picture is the result of double-ionized oxygen emission intermingling with the abundant Hydrogen. All exposures for this image were taken within 2 days of the full moon, which is something you can do with narrowband filters when the moon is around
