Wizard Nebula, NGC 7380 SHO (Star Correction)

I have been working on improving detail. This one of the Wizard nebula involved sharpening at the SHO level as well as a sharpened Ha imaged used as Luminance. This approach improved it quite a bit. I did not use BlurXTerminator though I will probably reprocess this with it in the future. The starless version allows the detail to be more noticeable and I will probably post a starless version as a revision.

The Wizard Nebula is an emission nebula with significant illumination in the OIII, SII and Ha bands when imaged over time. I imaged in over several nights beginning on October 8 and ending October 14, 2022. The primary source of energy exciting the gases comes from a variable binary star system 9.6Kly from the sun and seen in the image just below and to the right of the center of the image. They are the larger of what appears to be a binary system but they are so close together, they are not resolved in this image. Their orbital period is just 2.11 days. They are nearly identical and rare O-Type main sequence stars with an estimated age less than two million years. They are estimated to be 38 and 34 times the mass of the Sun.

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.
