A "10-second" shot of the Moon, 8 August, 2009

The sky was clear when I set up my telescope to image the Moon on 8 August, 2009. However, as I started to image the Moon, broken clouds started racing across the sky from the south (typical of San Antonio, Texas). I decided to wait a bit and see if it would clear up, but after a while it was evident it would not. But I noticed the clouds were spaced far enough appart that every now and then the Moon was visible for 10 to 15 seconds. I decided to shoot anyway, limiting each video capture to 100 frames, which with my laptop takes about 10 seconds at full DMK-41 resoltion. Amazingly, I was able to shoot 21 10-second videos and cover the entire face of the Moon. Upon processing the videos and assembling a mosaic of the entire Moon, I was happy to see the image was little different than what I can typically achieve in the average local seeing conditions when there are no clouds.

So, this image is presented not as an example of great lunar photography, but as the curiosity of being a 10-second snapshot of the Moon when it was technically cloudy.
