Good starting list. Just note, that once you get into DSOs, you'll likely want a different camera. Unmodified DSLRs are excellent for many things and they can pick up the faint hydrogen in many nebula but need a LOT more exposure time than dedicated astro-cameras or modified DSLRs.
So just remember to plan for that, because you'll soon look at your nebula pictures and notice that a whole night's shooting in a dark sky doesn't give you what others can get from more polluted skies and an astro-camera
