Mike, download the CCD Calculator from The New Astronomy Press website. It is great for modifying FL, Pixel sizes, FR and gives results of pixel resolution, images size in arcmin. You can even input and save cameras and scope dimensions that are not included in the supplied list.

I find it fantastic and would be lost without it when trying to calculate the best options for camera/scope/object.
