Broadband and Narrowband Astrophotography … What is the difference?

What is the difference between broadband and narrowband astrophotography.. Also, what is the most important piece of equipment for astrophotography? I have the answers to those with a look at several different nebulae and a special look at a galaxy hidden beyond the view of the beautiful Pleiades star cluster.
