Blue celestial sparkles - SNR G18.7-2.2 and PN G018.8-01.9

As in my previous image, Barnard 312, there were filamentous structures hinting at possible SNRs, and after having looked at some of the sky studies in Aladin, I decided to focus on an area nearby that the SHS H-alpha images suggested a possible SNR.
It was a pleasant surprise to see that OIII emerge like lightning! And if I had to give it a name it would definitely be Blue celestial sparkles!

I have not found optical wavelength images of this object anywhere and the only reference obtained is that it is apparently a possible SNR candidate G18.7-2.2 : https://arxiv.org/ftp/arxiv/papers/0807/0807.5004.pdf

I hope they like it as much as I do.

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.
