NGC 7000 - The North America Nebula in SHO

NGC 7000 in the constellation Cygnus is an emission nebula covering an area in the sky over four times the size of the moon. We're unsure of its distance from Earth but if the star Deneb induces the ionization of gasses causing light emission as some think, it would be ~1,800 light-years away.

This was my first attempt at narrow band imaging and processing. Ha data was captured in my backyard under a 3/4 full moon. Sii and Oiii datga captured at a Bortle 3 dark site.

Processed in Pixinsight, Lightroom, and Photoshop

DBE on each channel

NR with TVG and MMT per Jon Rista tutorial on each channel

Star removal on Sii, Ha, Oiii after saving Lum image from Ha. Used Starnet for Ha and combination of MMT and Starnet on Sii and Oiii images that were slightly out of focus. Wasn't able to remove all stars from Sii and Oiii so some aberrant star colors are present.

Stretched each channel and combined with Channel Combination.

Inverted RGB and applied SCNR to get rid of Magenta, then inverted back.

Used various color masks with Curves Transformation to adjust colors, saturation, and contrast.

NR on Lum frame using above TVG and MMT method

Local Histogram Equalization

Resampled at 40%

Minor global adjustments for exposure, contrast, saturation, etc. in Lightroom

Cosmetic corrections in Photoshop

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.
