NGC 7000 Cygnus Wall and LDN 935 in SHO

A detailed view of the Cygnus wall in NGC 7000 and LDN 935, which separates the North America and Pelican Nebulae. The ionization front in this image is very bright and each narrowband filter shows obvious differences in the structure. Dust in the the dark nebula is surprisingly detailed as well, with fine dark filaments that extend and swirl through the frame. Surprisingly, a small reflection nebula also shows up in the SII data (red patch on the left edge of LDN 935, near the middle of the frame).

Original = ‘Natural’ colors with H-alpha in red and OIII in teal/blue (HOO combination).

Rev. B = False color SHO combination, star colors created with Christopher Gomez's technique.

Rev. C = SHO tonemap with Ha luminance. Star colors created with Christopher Gomez's technique.

This data was completely acquired using my new EQ6-R mount. Compared to my previous EQ5, it significantly improved the sharpness and consistency of my narrowband frames. All masters were 2X drizzle stacked and treated with deconvolution, no additional sharpening was applied. Starless tonemaps were created using the StarNet++ plugin for PixInsight (developed by Nikita Misiura)

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.
