Astrophotography is expensive hobby. If you want to do quality pictures you must to invest quite sum of money. You must have mount which can track objects, probably guiding camera and guiding scope, imaging camera, some adapters, laptop etc. I begin with simple mount (EQ5) and with small but good scope ED80. I don't have this mount anymore because it was not good enough, but I still have ED80. We all make some mistakes at the beginning and we probably still are. I think that for beginning is very good choice Dobsonian based reflector. It is not suitable for astroimaging and it is not so good for observe planets in high magnifications but believe me that you must first learn the basic before rushing in astrophotography and dobsonian based telescopes are very good for that. And you don't need just scope for beginning but also some star maps or books, some eyepieces and most importantly you must go out, enjoy and learn a lot. It is not bad for beginning to see as much as scope that you can, ask people questions and of course read every post in this forum. Good luck in your quest.
