There are also app that lets you point your phone at the stars/ planets and they will tell you the names etc. Google sky map is one that I can think of but I know there are others as well.

should make sure to get one that has a red filter too , so you don't ruin your dark adaptation in your eyes.

By red filter, do you mean something that keeps red and blocks the rest, or the other way around?

Applications suitable for usage at night will have a mode that draws everything in black and red. It's based on the phenomenon that red light still triggers the cones (color-sensitive receptors in our eyes), while not overwhelming the rods (light-sensitive receptors), letting us use illumination (in this case for information display) without ruining adaptation to low light.
(Works best with AMOLED screens, where black = no light.)
