if you are going to get a reflector make sure it has a parrabolic mirror not spherical. unfortunately most of the cheaper ones like the celestron ones have spherical mirrors cause they cost a lot less to make. if you are planing on doing a bit of ap. avoid the celestron 127 eq reflector. it has another lense in the eyepiece holder to achieve a longer focal lenght than the short tube can deliver and a spherical mirror. this type of scope is called a jones bird scope. and this is what it does to pics. looks a lot better when you just look through one though.
