When you say resolve the rings of Saturn, do you mean just to have the rings visible as separate from the planet, or resolve the Cassini division in the rings ?

I think it would separate the rings from the planet. But not resolve the division.

I got this with my Pentax Q last month using a 1000mm f8.3 refractor. Justabout resolving the division in the rings despite it being low in the sky.

I've been tempted by the idea of buying a Ritchey-Chretien... maybe after I reach retirement age.
