Could somebody put it in terms that are quantifiable and not in high end optician language?
The issue of whether optical quality is justified for deep sky imaging is intimately bound up by the choice of camera and pixel size vs airy disc size. If you are using your eyeball, high quality optics will always win out as your eyes are capable of seeing the moments of clarity in even average seeing Planetary imagers who try to over sample the airy disc significantly with pixels will be fairly sensitive to mirror quality.

My attitude is that the lines of optical quality are probably more 'blurry' for prime focus imaging at faster f #'s but it helps to have good optics, but good optics will not help if you can't focus or guide properly.
