IC 5070 - The Pelican Nebula, and something else?

This was taken on my modified Zhumell Z130 at the unmodified focal length of 650mm. Since I'm not using any intermediate optics in the train (coma corrector or flattener) the surrounding stars are showing significant aberration in their shapes and some colors. However, I still think it's a beautiful image with what I was able to capture in the nebulosity, and perhaps educational as to why we need to use coma correctors and flatteners. The aberrations when using this scope with a 2x Barlow lens are significantly less prominent.

What's most interesting to me in this image is the straight-line wisp bisecting 56 and 57 Cygni. That trail is present in every subframe I have captured, and is stable over multiple nights and with dithering, so it's not an imaging artifact. But I haven't seen it in any other images of the region. I'm not sure what that is yet. I have some wide-field subs of the area as well, but haven't gotten a chance to process them yet. So for now it's an exciting mystery, at least to me.

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.
