Generally speaking, for deep sky you need more aperture (even more, in the long run, than 6 inches--152mm). For Photography the 100mm is more than adequate. What kind of photography are you talking about? What kind of budget. (A quality 100mm refractor will cost 10 times or more what a 152 mm reflector could cost).
