You really do need the camera attached directly to the focuser[assuming
that you have a DSLR], without a lens on it [prime focus]. Using a camera
aimed through the scope's eyepiece [afocal method] is only good for the
most basic of photos. If you buy a Newtonian make sure that it can be used for prime focus work, as many Newts cannot without modification.[ Skywatcher Newts can ].
