Here's an appalling picture taken tonight handheld with my mobile through my 5" reflector.

Satellites left to right, Europa, Ganymede (the bulge in the top left of the disc of Jupiter), Callisto (very faint and fuzzy) and Io.
Andd here's how it should look (inverted from mine with Ganymede against the rim of Jupiter)

The first picture's quite clearly awful but seen directly it's so clear. The moons of Jupiter are the jewels in the crown in the night sky.
You see a dot in the sky and it's just Jupiter. Look through even a small telescope and you see the two main dark bands on the disc and four diamonds near it that move position almost by the hour. Those four diamonds led Galileo to turn the Earth-centric view of the universe on its head and transformed our understanding of our place in the universe. Sends chills down my spine whenever I see it.

PS. Memo: must get an SLR mount for the telescope.
