Shadows of the North America Nebula - 1st Edition
Shadows Of The North America Nebula The North America Nebula NGC7000 captured in 2020 from Grand Mesa Observatory using a QHY367 Pro C full frame one shot color 36 Megapixel CMOS camera mounted on a Takahashi 130 FSQ APO Refractor telescope. Often ignored in images of The North America Nebula is the immense patch of shadows, the dark nebula LDN 935 appearing prominently (left of center) with the Cygnus Wall (at bottom left) and The Pelican Nebula IC 5070 (at center). The dust from this dark nebula obscures the emission nebula to form the region known as The Gulf of Mexico. This detailed image surely visualizes the nature of dust and gas clouds that populate the universe. In this Hubble Palette version (SHO) the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. RGB data was used for the natural star color, covering an area over 3 x 2 degrees of sky. Captured over 5 nights in May and June 2020 for a total acquisition time of 20.8 hours.
