Precisely what I've always done. My gear rarely changes so I get one image and feed to astrometry to plate solve. Regardless the web specs on your gear the variayions in manufacturing tolerances etc mean in practice they are not that precise in the end. Your image is exactly the fov you get so why not measure just that?
