Howdies there, i am a student too.
and have been saving buying saving buying making building saving buying for a while now
The numbers are scary when you put it in one pot and call it what it is. But first things first. ide go with a 8" dobsonian and just dip your fingers into the water with that. when funds permit your next purchase would be a NEQ6 mount following that (2 pieces together) Guide scope + Guide camera. Im gathering if your a uni student you have a laptop of some description. if so your a head in the game if not you can pick up a little eepc that will tie you over so they are quite cheap. following that you will need a camera i could suggest a small CCD camera something that has cooling.
By this time you will have a basic astrophotography kit. That will allow you to take images of nebula, planetary nebula, galaxies, stars, glob clusters ect ect. it wont be wide field (capturing alot in one image) but will be a good kit.
After that you can work towards a wide field system with bigger cameras, better mounts, field flatteners, ect ect ect skys the limit!
have a look at my equipment for a bit of an idea what a 10" dobsonian + Modified canon 40d mounted up on a EQ6 Pro mount (same as the NEQ6 just older).
