What can a regular person use to view the stars? My favorite thing in this world is looking up at stars but I live in NYC so I can't ever see stars. I was wondering if anyone knew of a device I can attach to a smartphone that would let me look up at the stars and actually see some? I can't afford to buy an expensive telescope. I'm a student and I just want to see some stars. Thanks to anyone who can help.
Binoculars.

This isn't going to attach to a smartphone, not everything in life is best seen through a screen. The camera on a smartphone is remarkable, but your eyes are much more sensitive in low light. Binoculars will make a lot more stars visible, even in heavily light polluted places.

A pair of binoculars is cheap enough for students. They are categorised as, for example 10x50, which means 10x magnification, and 50mm lenses. You want the second number to be big, which means the binoculars gather more light. 10x50 is often thought to be a good compromise between light gathering and weight. You won't want "zoom" or "night vision" or other such features.
