This is as much a photo challenge as a visual one.
Few photos are able to clearly show it. Many images show a diffuse and disjointed "ring". Others show nothing at all.
Good focus and resolution capability of the scope and camera are important here. If the image scale on the sensor is too small, detecting something here will be difficult if not impossible.
Up for the challenge with your camera or eyeballs? This is a very difficult feature for both. A test of optics, imaging, processing, and observing skills.
Conversely, what's the smallest aperture that the Cassini Division can be seen with?
