Is this anything? (Between RCW 120 and Sh2-2)

Here's a little ongoing project.
Last year I was scrolling around in Telescopius looking for dark nebulae to image. I came across what looked like an interesting clump of Hydrogen. So I collected some Ha at 765mm (in the revisions, monochrome). I was interested to see the radial / spoke type structure and the brighter central ring, surrounding a dark centre.

RA 17 08 12, Dec -38 14 50

Then the cloud came in.

Last week, at 300mm I took the opportunity to collect some more exposure. Sadly only 12 subs per Ha, Oiii and Sii filter at this stage. Image calibration will be far more effective with longer exposure as the nebulosity here is very faint.

First image is HSS mapped - definite Sulphur signal. I'll also include revisions with H(S)OO with and without stars. And SHO.

At the bottom right was something else unexpected: what appears to be an uncatalogued ? emission nebula with a faint Oiii signal included.

I have consulted many catalogues and maps. The image has been platesolved successfully. I can say the bright spot to the upper left is RCW 120. The Open Cluster right of centre is the Moth Wing Cluster NGC 6281. Off-sensor to the lower right is Sh2-2.

So I am publishing now to see if anyone is able to identify this object and / or make some assertions about what (if anything) might be happening here? It looks like gas is being dragged in toward a central point.

I'll spend some more time here this autumn/winter at 300 and 1000mm seeking to improve the image quality and resolve more details. I know the image quality is not good right now.

No, I don't think it's aliens.

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.
