Four SNRs and and more near Sh2-97 in Cygnus

Revision title: Image without annotations

I continue my hunt for rarely, if ever, imaged supernova remnants (SNRs)
In the first image I have made annotations of the following SNRs I could find descriptions of, all from this 2020 paper:
https://academic.oup.com/mnras/article/431/1/279/1042396
Three of them also occur (with a G-annotation) in D. R. Green's catalogue of galactic SNRs (https://www.mrao.cam.ac.uk/surveys/snrs/snrs.data.html)
1)    IPHASX J200002.4+305035 (G67.8+0.5)
2)    IPHASX J195744.9+305306 (G67.6+0.9)
3)   IPHASX J195749.2+290259 (G66.0-0.0)
4)    IPHASX J195920.4+283740 (not in Green's catalogue)

Finally I put a question mark on what looks like a possible planetary nebula or SNR that I cannot find in lists of PNs and SNRs. It is just below NGC 6842, a small PN.

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.
