Hi @ putrapetir, phenomenal hunting.
The device is easy to set, and  the content of 60 000 stars is really incredible.
Everyone loves to look in the sky with the stars, but in the city it is difficult to see the stars because of street lighting.
This projector gives you a lively look at the sky in your own home.
Everything you need is to have as big a ceiling as possible and to lighten all the lights in the room, so darken the room and the show can start ...
Indeed, the original solution for watching the stars.
