NGC 7000 + IC 5070 Mosaic


Click here for full resolution image

This image is a two-frame mosaic stitching two frames taken with the same (rented) telescope, two years apart. This is an area in the constellation Cygnus, the Swan, where huge amounts of excited hydrogen gas emit in its characteristic 656.3nm wavelength red light. The shape of NGC 7000 (on the left side) justifies its name of North America nebula. IC5070, the nebula on the right, is also called The Pelican Nebula.

This nebula is, if we refer to its magnitude, very bright, but its light is spread over a large area, and therefore, its surface brightness is very low, and not easy to image with enough quality. The zone that would correspond to the “Gulf of Mexico” is due to a dark nebula situated between the nebula itself and Earth.
