Segatoys HomeStar Planetarium

If you happen to be trapped in a city with bright lights all around and a little added “atmosphere” — or smog, as some like to call it — you should love this little guy. Instead of destroying small planets like the mini Death Star that it looks like, the HomeStar Planetarium ($240) recreates the constellations indoors for you viewing pleasure. It features a high-brightness white LED, a slot for different plates showing different groups of stars, six hour battery life, and an adjustable stand.
