IC5070 - Pelican - HOhOh

The Pelican is an iconic target but hard to process (just look at how few IOTD of this image exists on ABIN while there are probably 20+ pages of various versions).

After 3 weeks of head scratching and about 10 versions, I almost gave up but it was not reasonable to throw almost 24h of integration.

Color balance is hard so I opted for an overall compromise where I would get blue tones in the left part of the pelican, purple in the center, reds in the right part, pinks in the head and browns in the upperleft dusts and bottom center right of the body (see various image rev)

As always you are tempted to go overboard in terms of color saturation, contrasts , decon... Not sure I mastered it but now I can sleep peacefully and let this epic bird fly away.

Unfortunately the ZWO O3 filter is spitting out nasty halos that are very hard to process around large stars.

Deconvolution was very effective and recovered tons of details.

I also made the choice not to leave the image at it's native scale and denoising was made only in the linear stage with TGV.

Will revisit it next year by adding SII and we'll see what comes out of it.

Thanks to Cyber (Victor) for always being supportive and to Jon Rista for his initial feedback.

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.
