This bright emission nebula and HII region is very close to the Double Cluster of stargazing fame. The largest portion of the nebula is ionized hydrogen with a smaller oxygen region in the center. The target proved to be somewhat a challenge to process since the inner core is extremely bright compared to the more dimmer outer regions. So when processing is PixInsight, a combination of the MaskedStretch process and the ColorCorrectedHDRMT script were used to dim this area down and not be over-saturated.

Interestingly, the examples found on Astrobin and elsewhere seem to have no common color scheme, and each astrophotographer appears to have their own interpretation. While a medium blue seemed natural for the inner section, the fringes color proved a challenge to finalize, going through many shades of yellow with tints of green to reddish hues. The above is what I finnally settled on.

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.
