here are a few props you could use:
3d printer
bookshelf
computer
globe (season ticket)
laptop
ink and pen (w/ paper)
add some plants?
trashbin
sofas
pile of space trash (pretend u collected it )
I think that decorations/props are a good way to spice up a room. But when placing props, it’s important that you make sure to have the props fit the theme. Also, I would recomend to remove the telescope entirely. Also also make sure that there are just enough props too not make it feel too empty yet still little props to make it not too full
Maybe just a bigger more blocky version. If you want to take the cool route, make the telescope be out, flying in space like a satellite, and have like a side quest where you have to fix the telescope or something.
Here’s a fun telescope idea:
Have a hidden zone or button that, when you’re near the telescope, has a pop up (or camera point) that lets you look at the stars.
