The telescope: at least should have an opening 60mm refractor or 76mm reflector. As more bigger is the diameter better will be the pictures. The acceptable results are obtained from a 102mm refractor or 114mm, both must have a long focal length and equipped with equatorial mount.
A smaller proportion of focal length / lens diameter, means that more light is captured. This is not as important in planetary astrophotography because the planets are bodies shiny.
The equatorial mount is indispensable in astrophotography to orient correctly a telescope although the setting station is tedious (especially when the observer is a beginner) the results are far superior.
Camera: for planetary astrophotography cameras are not needed very sophisticated, even with a simple web-cam get excellent results. We recommend using those that allow manual control of things like white balance, etc. Actually, what you do is shoot a video and then with a program like Registax, proceed to stack the images so that it is a single image. The camera must be connected to a computer and it must have installed the necessary software for operation.
