I stayed up waaaay too late watching this thing. You can set it it to display just stars, planets, or both and watch it move. I ordered a cheapo unknown brand one from Amazon and tried to put it together on NYE. I ended up getting so frustrated and drinking a bottle of wine because all of the instructions were in Chinese and evidently it needed a cord with a port combination I have never seen before in my life. Tonight I’m gonna try to put its slides in the smithsonian projector and really go star crazy.
