North American Nebula in the region of the “Pelican Nebula”

I hesitate to label this strictly an “artistic rendition” because what you see is really there, just not usually so obvious. Among my many experiments on how to bring more detail to my images, I experimented with various implementations of a thing called a Sobel Operator. Although most implementations of that operator have been tuned to enhance edges, the operator actually delineates slopes or gradients in brightness and color. My coding steps back and simply stops at recognizing slopes In effect, this image portrays the first derivative of the parent image. You should think about viewing a mountain at the low illumination angle of sunset or sunrize--a prime time for photography or painting! This image is similar to that, except in this image the sun sets to the North, East, West, and South, all in the same “painting.” That is, gradients in all directions become pronounced; consequently, the structure and chaos of the nebula comes to the fore.

Comments always welcomed!

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.
