I've always heard and read about the "Lunar Cross" that can sometimes be seen at the lunar terminator near the craters Purbach and Blanchinus. Thanks to Dana on the Astromart "LUNATICS" forum, I got warning of the occurrence of this phenomenon in advance. This is basically, from what I gather, the formation of an apparent cross of light when the lunar terminator settles over a certain set of lunar features.
I saw it for the first time tonight, and it was pretty neat. So-much-so I decided to take a photo of it using the Philips Toucam and my 8" LX200. It's an okay image, I still have a lot to learn on that front but at least I captured it. Click on the image for the full version, you can see it at upper left.
