North America Nebula & Pelican Nebula (Widefield)

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

A wide field HOO bicolor composition of the North America nebula and Pelican nebula, aiming for a more natural look under bright moonlight rather than dramatic narrowband colors. Starting with red = 1*Ha, green = 0.1*Ha+0.9*O3, blue = 0.15*Ha+0.85*O3, O3 is stretched a little more than the Ha, result is the highlight area is a more neutral grey rather than red or blue.

The narrowband subs are quite noisy, along with many line defects. It took me hours of learning and trials to give it a more pleasant look. The outcome is satisfactory, I like the wide field that includes both north america nebula and pelican nebula, also with Deneb shinning brightly over them.

Processing:

Pixinsight: Line defect extraction and subtraction, HistogramTransformation, PixelMath, TGVDenoise, SCNR

Photoshop: Curves, Saturation

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.
