Most scopes are not designed for astrophotography, and even fewer are designed for astrophotography with a full frame sensor. To produce a 'flat' and close to fully illuminated field across a 35mm sensor is a tough job. A typical Schmidt-Cassegrain, Newtonian and most affordable refractors will not do it. You need a scope that is designed for imaging.. if so it will have specs for its image circle and perhaps even the 'spot size' at the centre and edge of the frame. Look at the types of scopes being used with big sensors in the Astrophotography gallery or anywhere else online. It's considerably less demanding with a cropped sensor camera.
