NGC7000 North America Nebula

This is a 2-panel mosaic of NGC7000, The North America Nebula, an emission nebula in the constellation Cygnus (The swan or “northern cross”). It is estimated that this nebula lies 1,800 light years from Earth. However this distance is not exactly known.

The shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. This nebula and others nearby are parts of an interstellar cloud of ionized hydrogen. Between the Earth and this nebula complex lies a band of interstellar dust that absorbs the light of stars and nebulae behind it forming the shape seen in this image.

The Cygnus Wall component, which is easily seen on the “western” side of the Mexico shape, is a super-concentrated area of star formation.

Because its surface brightness is low, it cannot be seen with the unaided eye. Its reddish color is due to light emitted on the hydrogen alpha (Ha) spectral line wavelength which would appear deep-red to our eyes. The imaging camera (Canon T4i) was modified to replace the factory IR-cut filter to allow the Ha wavelength to pass through to the imaging sensor.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
