Ringed galaxy candidate, a Cat's Eye.

It looks a little like Eric post # 25 above 587730847960400171

Noted object at target's NNW looks like it is passing in front of and over this galaxy.

Ringed galaxy, UGC 09480, an ACW spiral has a faint outer ring.

Noted target is an High Surface Brightness object that appears to have a faint tail. 

Also 2 objects at target's SSW and SW may be generating a material streams.

Ringed galaxy candidate.

An ACW spiral that has an almost complete outer ring and a complete inner ring. 

Noted that there may be an inner ring around the central bar, but it is too fuzzy to decide.

Ringed galaxy candidate.

ACW spiral with an apparently single arm that makes greater than a 720 degree wrap around galaxy. 

Also arm appears to be attached at target's west end. 

Brighter knots on ends of central bar and a separate c-shaped cloud at the NW.

I am not sure where this one belongs, so I'll try it here. 

Weird, ringed galaxy candidate with an apparent polar ring around the possible CW spiral inside.

Ringed galaxy candidate is a barred ACW spiral.

Noted that the ring appears to have a CW spiral where the arms are disconnected from the inner central bar. 

Also noted a small object at SE that has faint material streams pointed back toward galaxy.

Ringed galaxy candidate.

2MFGC 12613, an ACW spiral may overlap or may be interacting with smaller ACW spiral due east.

Ringed galaxy candidate, blue color, CW spiral with almost complete ring.

Noted small object at target's west appears to have a faint tidal tail that arcs back to this galaxy.

Ringed galaxy, CW spiral with a blue inner ring. 

Noted a polar ring or helix ring around outside of galaxy.

Inverted color image shows the polar / helix ring better;

Ringed galaxy candidate, inner ring appears to be an CW spiral. 

Outer ring appears to be two ACW spiral arms with spokes. 

Inner ring looks almost heart-shaped.

Ringed galaxy candidate, barred, ACW spiral with ring offset from core. 

Noted that either of two objects (one at NE and the other at SSE) may have interacted with the target galaxy.
