I wanted to start astrophotography.
Let's assume that I want to take pictures of planets when they are the closest to the planet earth, which planet would look the biggest thought a telephoto lens? Some planets are smaller but closer to the planet earth (Mars), some are more far away but way bigger (Like Jupiter), so I don't know which planet is the easiest to take a picture. I know that a 800mm lens with an APS-C camera is enough to see some small details of Jupiter, but what about the other planets?
