Swan Nebula reprocessed with BX2 AI4

I took this picture at Grand Canyon National Park during the Astronomy Party in June. My mobile rig is a 6" Celestron with v4 HyperStar and ASI 2600 mc as my primary imaging camera. I believe the large sensor and the steep light cone causes coma on the edges that do not come out with calibration frames and processing. Until now. I performed WBPP in PixInsight, and then processed using my workflow (DBE, SCNR, SPCC, BX using the new AI4, NX, SX, Hoo normalization of starless image and then GHS, arcsinh stretch of stars, and pixel math to recombine). The new AI for BX is really showing its power to reduce coma and diffraction spikes.

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.
