Been a while since I last posted a photo of the Moon. This was taken with my 70-300mm zoom at 300mm focal length with an exposure of 1/1000 seconds at f/5.6, ISO 400. It's hard to do any better with this particular lens - I need a nice telescope. Despite the low resolution, you can see a lot of detail on this nearly last quarter phase moon. The bright rayed craters Kepler, Copernicus and Tycho are all visible, though Tycho's normally spectacular rays are a bit subdued in the late afternoon sunshine at that site. The bright crater Aristarchus is visible near the eastern limb (as we see it on the left - western limb if you were standing on the Moon) looking like a spotlight in the middle of the dark Mare surface around it. At the moment this was taken on Saturday night (10/18), it looks like the sun was just setting on Tranquility Base where Apollo 11 landed more than 39 years ago. Another Lunar day has gone by without new human bootprints on our nearest neighbor.
