I hit 50 nights of tracking Jupiter's moons and it changed how I see the sky

Started counting back in February just for fun. Used a cheap 4.5 inch dob and a notebook. Last night was night 50 and I could actually predict where Io would be before looking. It surprised me how much you notice small shifts in motion over time. Has anyone else tried tracking a single planet for a long stretch like that?

Funny how learning one small thing teaches you patience with everything else.

Yep, that's exactly how it works. @taylorhunt is right that tracking something night after night changes how you see it. Once you put in that kind of time watching one small thing, you start noticing all the other slow changes around you that most people just walk past. It's like your brain gets rewired to pay attention to details you used to ignore.

Read somewhere that Galileo's original sketches of Jupiter's moons were basically just him noting positions night after night in a little journal... like what you're doing but with way worse optics. It's wild to think he figured out they were orbiting Jupiter just by watching those tiny dots shift back and forth. Your 50 nights thing reminds me of that old idea that you don't really see something until you track it over time. The little changes add up and suddenly the sky feels less like a picture and more like a living thing moving around you.
