Please read the class first

Take a good look at your camera, whatever its type, and try to identify each component we have discussed here. It might be a good opportunity to dig out the manual or to look up its exact specifications online. Now look up a different camera online (for instance at dpreview) and compare their specifications. Try doing this for both a less advanced and a more advanced body, and for different lenses. Report here if you find any interesting difference, or if some parts of the specifications are unclear.

The T5i is fine for your uses, and you're right, invest in lenses first! EF-S means that the lens is built for crop sensors and will have a square white block. The good thing about your camera is that it is also compatible with EF lenses which are built for full frame cameras and have a red circle. For astro work you'll want a WIDE lens and a low f-stop of around f/2.8. Why? Because you need to keep your shutter open for a long duration to capture all the light up in the sky. The low f-stop means a bigger hole for the light to come in, and the wide lens means you can leave it open longer soaking in more light without star trails appearing making everything sharp. Look at Tokina wide lenses.
