Gerald say: You may have a chance to see Titan, the largest Moon in the Solar System. But you will need a good eyepiece and a good dark location with transparency and steadiness.

Tethys, Dione, Rhea and Iapetus are possibilities as well but they are not easy objects.

aladdinwa say: None. I once observed Jupiter through a 250mm telescope in an observatory, and saw only the four largest moons of Jupiter. Saturn is much farther away, which means it and it's moons are dimmer, plus Saturn's moons are smaller than Jupiter's. You have no chance of seeing Saturn's moons.
-
Iridflare say: It depends on you - I've never seen more than 2 (with a bigger 'scope), but I know someone who can see 7!
-
quantumclaustrophobe say: I think you might see Titan... I doubt you'd see any of the others.
-
poldi2 say: If conditions were perfect you might see Titan. But none of the others.
You could see all 4 Galilean moons of Jupiter.
-
Sharon say: Titan, plus probably Rhea and Dione. Maybe Tethys
-
daniel g say: I would say two when visible.
What Dobsonian scopes I have seen have some decent optics, more bang for the buck they say.
-
Ninefinger say: Depending on your location. At least two, maybe four in optimal conditions.
