Am gasit pana la urma in Wikipedia :

" The Cassini Division is a 4,800 km (3,000 mi) wide region between the A Ring and B Ring. It was discovered in 1675 by Giovanni Cassini at the Paris Observatory using a refracting telescope that had a 2.5 inch objective lens with a 20 foot long focal length and a 90x magnification."

Ce sa zic....foarte tare ! 
Oricum avea un cer foarte curat in acea vreme, plus ca probabil inelele erau inclinate frumos astfel incat a putut distinge bine diviziunea.

Despre inclinarea inelelor ne poate lamuri Stellarium daca setam anul 1675. :)
