First North American Nebula

Cygnus is rising now, and that means I can shoot some really large nebulae in the area with the new Raptor61. North American Nebula seemed like a perfect target to shoot.

Description: Original stacked TIF taken into Siril, then the following steps:

Tighter crop

Photometric Color Calibration

Background Extraction to deal with LP gradient

Channels extracted to individual TIF's for Starnet++

Recombined channels for starless and stars in Photoshop, then final levels/curves adjustments and some noise reduction performed using Astronomy Tools Action Set.

Much happier with this version.

Description: Another revisit to old data. I'm learning more about how to use selective masking in photoshop, and the power it holds for highlighting the nebulae.

I'm on the fence as to whether I went too far with this one, but I kinda like the more natural colors of the center, and the cygnus wall and pelican being more pronounced in red.

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.
