You are right the planet Jupiter is not the brightest object in the sky. The planet Venus is and then the Moon (when its in the sky). Jupiter is however a very distinctive and easy to find object with the unaided eye. And for your second comment, again you are right, everything is easier, once you know what you are looking at/for.Hmmm... I'm not too sure about the assertion that Jupiter is the brightest planet. Venus is brighter.
It's actually much easier in real life, once you get used to it.
