Yeah, naked eye, although with a 6” telescope, I’d expect it to be a bit fainter - certainly that is the case through my 9.25” scope. I can often see a band in its rings.

It also depends a lot on atmospherics, if there is a lot of turbulence in the atmosphere it makes things less crisp (well, “dancey”, like looking through a heat haze.)

Look up your local astronomy group and go along one night, and see for yourself before buying anything. Saturn isn’t great at the moment (assuming London-ish latitudes) but Jupiter is around all night and you should be able to see it through a variety of scopes and eyepieces if you went along to a sky party.

Honestly, the first time I saw Saturn through a telescope I nearly cried. Truly amazing.
