If you follow astronomy, Jupiter is very bright in the evening sky. I thought I would see what I could do with my Swarovski spotting scope. I aimed it and at 20 power magnification, I could easily make out the planet Jupiter and four of its moons. I was even able to digiscope it with my Nikon D40:

I managed to capture it--a bit shaky but still, you can make out the large planet and two moons on either side. My eyepiece zooms up to 60 power and when I did that, you could actually make out the cloud rings on Jupiter. Alas, I was not able to digiscope that but it's cool to know that the spotting can be used for more than just birds.
