Luxury! When I was a lad we only had a 2.4” to see the Cassini division.
I have seen the Cassini division a few times with a Tele Vue 60 (2.4”). Just need excellent seeing, a wide open ring system and the planet closest to Earth as every km counts. Seeing probably the most critical.
Looks like I need to get a smaller telescope. A TV-40 has a nice ring to it.
