Description

The North America Nebula NGC7000 in bi-color captured earlier this year using the QHY367 Pro C full frame one shot color 36 Megapixel CMOS camera mounted on the Takahashi 130 FSQ.

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 Narrowband version (HOO) the H-Alpha is mapped to red OIII is mapped to the blue channel and blended to the green channel, with RGB data used for the natural star color.



Captured over 5 nights in May and June 2020 for a total acquisition time of 16.5 hours.

The data used in this image is available from Grand Mesa Observatory Subscriptions, System 1.
