North American Nebula
The North America Nebula (NGC 7000) is a prominent emission nebula located in the constellation Cygnus. It derives its name from its resemblance in shape to the North American continent. Situated at an estimated distance of approximately 2,600 light-years from Earth, the nebula spans a physical radius of about 45 light-years. With apparent angular dimensions of roughly 100 × 120 arcminutes, NGC 7000 is a substantial object in the night sky—over three times the angular diameter of the full Moon.
NGC 7000 forms part of a larger interstellar complex, sharing a common region of ionized hydrogen (H II) with the nearby Pelican Nebula (IC 5070), visible more faintly in the upper right portion of the image. Although cataloged as distinct nebulae, both structures are physically part of the same emission region, separated visually by a prominent dark lane of obscuring interstellar dust.
This image was made with a Nikon Z7II and a Nikon 400mm f/4.5 lens. A total of 75 30-second images were taken at ISO 3200 for a total exposure time of 37.5 minutes. Star tracking was done with a Fornax LighTack II. The raw images were converted to TIF using RawTherapee, which were then aligned using Deep Sky Stacker. The star aligned images were then stacked using a simple average. The stacked image was then stretched and color corrected using astro-color-stretch. Python program astro-color-stretch is available here in the astrophotography software downloads page. Final editing and noise reduction was done in Capture One and Topaz DeNoise AI.
