Yes, most definitely a tripod shot. The four dots are definitely the four "Galilean Moons" based on not only their spacing but their planar orientation at the equatorial plane of the planet. The planet, being a gaseous giant, is oblate, meaning spun wide at its equator due to tidal effects and centrifugal forces. That the four small dots are clearly oriented along the imaginary equatorial plane is proof enough that they are the four largest Jovian moons, Io, Europa, Ganymede, and Callisto.

A very nice image!
