I was rather thrilled late last Friday evening (after more than a few beers + smirnoffs) to see for the first time ever Jupiter being more than a simple bright dot in the sky... it was the first time I saw Ganymede, Callisto, and Europa, too. If I could hold my binos steady enough (no mount yet) then I might have also been able to see Io.
Finding out that the fuzzy blue spot a little bit below Jupiter was actually Neptune made me laugh out loud.
And to think that somewhere in that FOV was the object that would hit Jupiter shortly thereafter... amazing
