Collection of Rings and Distortions, With Images
Most galactic rings are dismissed as an illusion, a result of a suspicious mechanism called a gravitational lens. This lens is a source of gravity claimed to bend the light of a more distant object to appear as a distortion like an arc or circle or to appear in a location where it should not be.
Following is a collection of these distortions with images. Many are claimed to be the result of a gravitational lens.
Each distortion has a link to a description and a link to its image (if available separate from the description). I hope the links remain intact.
To bring all these images into one topic would be a very large page on a display screen.
This way you choose the topic or just the image.
These are in no particular order.
Hoag's Object is a known ring galaxy.
from Wikipedia:
'
In the initial announcement of his discovery, Hoag proposed the hypothesis that the visible ring was a product of gravitational lensing. This idea was later discarded because the nucleus and the ring have the same redshift, and because more advanced telescopes revealed the knotty structure of the ring, something that would not be visible if the ring were the product of gravitational lensing.

The criteria about knots is not applied consistently because many other rings show knots but are still claimed to be a distortion by a lens.

Here are rings and arcs claimed to be distortions.
They are in no particular order.
Einstein Cross or QSO 2237+0305 - four nodes around a central node; claimed to be four lensed images of one quasar, the one in the middle.
The simpler explanation is five quasars in close proximity with a possible coarse alignment. Halton Arp observed quasars with the same red shift in pairs.

Abell 2261 - arc at 9 o'clock; some documents mention knots in Abell 2261.

Abell 383 - long arc at 4 o'clock ending with a knot; beyond that at 5 o'clock is elliptical with distorted circle.

Abell S1063 - several arcs around the elliptical

Abell 1413 - arc at 10 o'clock

Abell 2667 large arc to left of large elliptical, the bottom of the arc has a knot

Abell 1835 could have a jet at 1 o'clock to the very bright central object

Abell 370 - large arc at 2 o'clock to central elliptical; the bottom of the arc has a knot
link

SDSS J1004+4112 - the central bright object is claimed to be a lensed quasar (which don't have jets) but it looks like an elliptical with a long jet at about 10 o'clock; there is an arc with knots at 4 o'clock with another small arc above it; there is also an arc at 2 o'clock that crosses a distant galaxy - quite the coincidence!
When zooming into an image there is another elliptical some distance away from the main one at about 9 o'clock. Oddly this one has an arc with knots at 10 o'clock. Near the right edge is either: two galaxies are merging or one is splitting. Below that is two spirals with long tails. This is a very interesting cluster.

The Twin Quasar - adjacent identical quasars are not allowed so they must be an illusion; there are 2 adjacent bright objects in the image; the right one in the pair might have a ring; at about 2 o'clock from the quasar pair at some distance is a reddish ring galaxy.

Abell 1185 - in APOD image: at the left is an elliptical with a very long jet with 2 disorganized nodes; this is image is here for that jet, not as a lens.

Abell 2744 wikipedia has a terrible image with false reds and blues; zoom into the image below; the lower elliptical to the right of a bright spiral has long jets at 2 and 6 o'clock; there is a distant filament at 4 o'clock; the elliptical at 10 o'clock to the one noticeable bright yellow star has filaments at 5 and 10 o'clock

nor does it identify the distorted galaxy.

Many of these distant cluster appear to exhibit much electrical activity as arcs. Perhaps others will find even more features than the obvious ones after zooming.
I found more of these 'distortions' than expected. I expect there are others but those have no available image.
