I want to thank everyone for their kind comments on the reports. Today's regional newspaper ran a feature story on the photography of Dean Hill, which remind me of the beauty brought out by the Vixen Foresta binoculars. A photo of a mature Appalachian forest that I particularly admire is Hill's "Sit Among Giants." Here is a link to the feature story in today's newspaper -- Dean Hill's Appalachian Photography .
. . .
There are more comparisons I want to make, but those reports will have to wait a week or two.
. . .
One observation that is beginning to haunt me is fog/haze penetration. The Fujinon appears to be better at penetrating high humidity conditions on the ground. In comparing other models at different times in the past, I have noticed Nikon binoculars also appear to do quite well at haze penetration. How does haze penetration affect night sky observing? I hope others can offer comments on haze penetration.
Once again, I want to emphasize both the Vixen and the Fujinon models are premium porro binoculars and the 7x50 size is an important size. As my comparisons continue, I will try to present some of the benefits of the 7x50 size. If you have one or more 7x50 models in your selection, I hope you can take them outside and appreciate the benefits this size brings to observing.

Observation
Moon at transit -- 180° azimuth, 35° altitude
Waxing gibbous with 72% of disk illuminated -- Moon phase
Day 10 -- Moon age
Moon and Jupiter 10° separation
Fujinon FMT-SX porro IF 7x50 shows a yellow ring around the Moon, with yellow rendering across the disk.
The Moon is most pleasant with the Vixen Foresta porro CF 7x50, which reveals the Moon's color close to natural as seen with my naked eye. Tonight, the Vixen view closely resembles the view through Nikon SE binoculars or an APO refractor telescope. In other words, the Vixen presents the Moon very close to perfect.
The prize tonight goes to the Vixen.

Observation
Orion constellation

Taurus constellation
Specifically Hyades (Melotte 25) and Pleides (M45)
Vixen Foresta porro CF 7x50, as with previous observations of star patterns, fails to present the stars as brightly as the Fujinon FMT-SX porro IF 7x50. Furthermore, the Fujinon shows more nebulosity around the Great Orion Nebula in Orion's Sword. Neither binocular reveals the nebulosity in the Pleiades (the veil worn by the Sisters). The jewels in the Hyades sparkle brighter in the Fujinon. In Greek mythology, the Hyades were the five daughters of Atlas and half-sisters to the Pleiades. After the death of their brother, Hyas, the weeping sisters were transformed into a cluster of stars that was afterwards associated with rain.
As a naked-eye object, the Hyades Cluster has been known since prehistoric times. It is mentioned by numerous Classical authors from Homer to Ovid. In Book 18 of the Iliad the stars of the Hyades appear along with the Pleiades, the Big Dipper, and Orion on the shield that the Hephaistos made for Achilles. I did not measure any difference in binocular limiting magnitude (BLM), but the stars in the Vixen lack the contrast displayed in the Fujinon. Again, I do not have an explanation for this difference. Perhaps it has something to do with the Fujinon's yellow rendering being better at penetrating the moisture reflectivity of the sky? Just a guess. I did notice the Fujinon did a better job at penetrating fog and haze during land comparisons. Maybe this moisture penetration has a difference on night sky observing? I do not really know. I am only guessing about the difference. Perhaps the optical engineers will come into this thread and venture an explanation.
Just like the Greek warrior Achilles, the mighty Fujinon musters up to capture the prize of this morning's beautiful autumn sky. Let us all shout for the Fujinon, who fails to lie down when faced with new competition.
