This was taken with a D800 at the prime focus of an astronomical telescope, a 155-mm Astro-Physics apo refractor. The atmospheric "seeing", as we say, was pretty bad, limiting the sharpness of detail on the Moon. The sharpness and resolution are comparable to those of Jim's image through a Televid of half the aperture, suggesting that he had better seeing, possibly because when I made my image, the Moon was still fairly low in the sky. In any case, this shows that as I noted last night, Jim's image is pretty good for three inches of aperture (as we express it in astronomy). Through a telescope visually, it always looks better than in simple images like ours. I'd still like to see Jim's image in the original. You can plainly see a grainy texture in his that isn't there in mine and I wonder whether it's coming from processing or what, and I think it could look better. ?howard
