Astrography is the art of describing or delineating the stars.
Astrophotography is photography of celestial objects through a telescope. You can do this with any telescope that can be adapted to a camera, but is best done with an instrument that has a clock drive so it can stay aimed at the thing you're photographing. Very large telescopes, like the ones at Palomar Observatory, are only used for astrophotography. There is a word "astrography". It means making a star map or describing the stars.
Oh, dude, that's like astronomy but with a cooler vibe. It's called astrophysics, and it's basically the science of space travel, black holes, and all that cosmic jazz. So, yeah, if you wanna be a rocket scientist, you gotta be all about that astrophysics life.
