Tonight Tried to make foto of Jupiter with my canon sx50, but perhaps exposure 8/10 is too long?
 
Jupiter is a very bright planet, and it is possible to get some kind of detail on it using just an everyday camera with a long telephoto lens. However, if you want the best quality images of planets you should look into webcam imaging via telescope.

Here is a quick pic taken with a 400mm lens at f5.6 for 1/30 sec at ISO 200

Looking at your EXIF information, if 215mm FL is 35mm equivalence, and it probably is, then I would keep the shutter speed to 2 sec or less to prevent trailing of the moons and elongation of Jupiter. Your exposure level for capturing the moons of Jupiter is about right, maybe just a little brighter would help. So try shutter of 2 sec, ISO 400, and aperture 6.5 to get the same brightness of exposure but in less time. Then try a much faster shutter to get a dimmer exposure level of Jupiter like Steve showed. Then combine the two images to form a composite view of a dimmer Jupiter and brighter moons.

What I've tried with Jupiter is first adjust exposure to ensure that the histogram doesn't clip in the highlights. This can be difficult to see since Jupiter may only occupy a small portion of the image. Then with a pixel editor like Photoshop Elements, I select just the disc of the planet and adjust levels to best show details. A similar process for selecting just the moons allows adjustment for best visibility. This allows for keeping the background dark without unnecessarily darkening the disc or moons.

Jupiter like all planets is hard to post process since many of the image details are of very low contrast, difficult to pull out. But here are a few examples:

By the way the free iPad app "Gas Giants" is very useful for identifying moons, shadows, etc. Also it helps plan for interesting events that might be photographed like transits of moons and moon shadows.
