NGC 7048 evolved planetary nebula in Cygnus HOO image

II couldn’t find a lot about this wonderful planetary nebula NGC7048 in Cygnus except that it is about 5300 light-years away and that it is an evolved planetary nebula oriented 90 degrees to us, and that the progenitor star is probably a white dwarf. Since it is evolved it is of low surface brightness and represents a planetary nebula that is old and thus potentially represents the final stages of the nebula’s dissipation—though appearances suggest it is holding together well, except for the one section that does appear to be dissipating.

Even a simple stretch shows the outer ring, about 1' in diameter, is very red in my L-eNhance and L-eXtreme filters due to the Halpha signal, so I kept that very red color in my processing. Both Registax and AFP-R (which is used by NASA) were used to bring out details and contrast in the nebula. A few of the stars are very bright and easy to bloat so I processed the stars separately and kept them muted to the background so to speak, to allow focus on the nebulosity.

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.
