Awesome in Blue

image by " rel="nofollow Thierry Legault, Paris, France

Thierry is one of the world's best lunar and planetary imagers. As evidence I recommend that you browse through some of his wide-screen lunar " rel="nofollow images or perhaps one showing an astronaut taking a " rel="nofollow spacewalk. Today's blue LPOD is exceptional for it shows a thin lunar crescent with a calculated lunar age of exactly zero. The reason a crescent is visible at all is that the Moon is 4.4° from the Sun, a tiny amount, but enough to make a picture just barely possible. Thierry's " rel="nofollow website shows the special sunshade that helped incease contrast to make the Moon visible - after stacking 4000 images. I don't think we learn anything about the Moon from images like this, but the challenge is great and the accomplishment awesome.
