Anyway. Do you believe that any details that our
eyes can see such as 400X in jupiter can also
be seen by the digicam?? Or are there details
where only our eyes can see that can't be
seen by digicams (in the same scope)?

It's a complicated question. There is no doubt that any camera
significantly outperforms the eye in almost every respect. But when you
look at a planet, you will occasionally see brief moments of very high
resolution. That sort of thing is difficult to catch with a DSLR; a
webcam or other device is really the tool for planetary imaging. Still,
in most cases even a DSLR will catch much more than your eye.

The webcam or a DSLR running in fast frame capture mode will eventually get a shot of lucky seeing. The human eye persistance of vision prevents us seeing clearly through a turbulent atmosphere.

As Chris says price peformance wise a Webcam is the way to go for amateur high resolution planetary imaging at maximum possible resolution. Even the professional astronomers have been at it (although with somewhat more exotic kit).

Almost no professional astronomy is done visually these days.
