I photographed some of those moons with a C-20
The main student telescope at Stanford University is/was a Celestron C20 (20 inch diameter). For my astronomy project I photographed the moons of Uranus and did their celestial mechanics (calculated the mass of Uranus). It was good fun. The innermost moons Miranda and Ariel are hard to do because they get washed out by the light of Uranus. Because the obliquity of Uranus is almost 97 degrees, the moons are almost always visible and not eclipsing or transiting the planet's disk like the Galilean moons of Jupiter often do.
