Astronomy is very much a mental and conceptual pursuit. If one hasn't considered the vastness of space, the time it takes to get anywhere, the forces acting across space or the history of the Universe, then objects within it may look a lot less awesome.
One fact that piqued my interest early on was when I first learned that an astronaut returning to Earth will have aged less than the people who stayed back on earth, due to the way time and space interact (travel faster and less time elapses relative to the point of origin) - how weird is that! So jogging is good for you
Watching Star Trek probably helped to develop an interest in space too
Then I get a kick out of thinking about optics and how light bends as it travels through different mediums (and different glasses in a refractor).
There's also the Mechano aspect, playing with and adjusting mechanical devices, and the Jewelery aspect - scopes and even mounts can be pretty to look at.
So like any other hobby it's what you make of it and there's no right or wrong way to enjoy it (or not, if it's not your thing). When I was younger I spent a lot of time on dirt bikes and hang gliders then family responsibilities made those less important and finally health issues brought the sedate hobby of astronomy to the fore.
Edit: forgot to add a big one, the possibility of life elsewhere in the solar system or universe holds endless fascination
