I am going to be working on a project where we will be imaging the full moon with an ultra high resolution camera (more than double that of high end full frame DSLRs). The goal is to utilize the camera's high resolution. Which telescope would provide the sharpest and best image of the moon? A reflector or a refractor? It is said that refractors provide higher resolution at a given aperture, but refractors are generally less than half the diameter of reflectors at similar price points. How do you compare apples to oranges here as far as optical resolution goes? I provided a couple of potential telescopes that we may purchase for the project. I am open to suggestions to other telescopes as well. I imagine we would not want to spend more than $2,500 for the telescope and field flattener/coma corrector. The camera sensor is a super 35, which is a little bigger than a APS-C, cropped DSLR sensor.
