Jerry,
Nice review. That must have been alot of work.
Because of the way these cameras acquire color ( not all the pixels
are used at once) they will not have the same resolution as the monochrome
astronomical CCD cameras. Also the blue halos and distortion of the stars
are more likely due to the performance of the 400MM F2.8 lens. These lenses
are not apochromatic or even close. CCD's will bring out all these optical
flaws.
With film the optical flaws of these lenses are masked by the overall low
resolution
of the image.
