Cronus (Saturn) was the son of Uranus and Gaea. Cronus and Saturn were the Greek and Roman respective Gods of Argriculture.

Cronus (Kronus) is also the Greek God of Time and youngest of the Titans. Cronus lead his brothers and sisters, the Titans, in a revolt against their father and became the king of the gods. He married the Titan Rhea.

The ~4800 km wide Cassini division is very visible in this image, and separates the A and B rings, two of four major and three minor rings (each comprising thousands of individual ringlets).

Galileo Galilei first saw the rings with his third version (30x) refracter, but miss-interpreted them as three closely-spaced bodies. Galileo described the rings as "Saturn's Ears". Christiaan Huygens was the first person to suggest these were rings (using his much better 50x telescope). Giovanni Domenico Cassini subsequently noted gaps between the rings, of which the largest is named the Cassini Division.

Imaged 4/4/2017 with a Skywatcher 8 inch Newtonian from Boronia (Melbourne).

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.
