Jupiter with shadows

At Frisco Starfest on Aug 8 we were treated to fairly decent views of Jupiter. The clearest I’ve seen yet, due to the fact there aren’t any heat-releasing houses surrounding the scope.

I thought that there were two moon shadows but it turns out that Callisto is dark enough relative to Jupiter that I could see it along with the shadow it was casting onto Jupiter.


Callisto is the lighter dot toward the center of Jupiter and its shadow is to the right of that.
