Saturn tonight in the 120 eon

Hi,
I just had an awesome time with Saturn.
When the smoke of the chimneys in the area weren't interfering I had beautiful crisp views and yes the rings are definately opening up. It is slight buth there was a clear rounding of the ring and the slightest of space in the curve of the ring. I wonder when the earliest possibility of catching Cassini in a 120 refractor will be?
Clear Skies

Before the humidity hit I was also able to get some viewing time here in NC for about an hour on Saturn. This was with a 150 mm f/8 newtonian, the best views coming with a 9 mm Nagler and 7 mm Pentax XL. I am just a beginner, but it is my impression that I am seeing more banding on the globe at this time. It may just be that I am observing better.
