The edges of the lunar landscape

Here, we are peering slightly around the north east (top right) side of the moon, due to it's slightly wobbly path around us here on Earth. This libration effect has made the lunar sea Mare Humboldtianum visible behind the crater Endymion. The slight fuzziness of the image is because the jet stream was over us again, which resulted in not so good seeing conditions. Also I was looking through a fairly large air mass. It was taken with the society's Imaging Source DBK camera using a 2x barlow lens, on a Celestron 9.25". I tilted the camera and overlaid two images that were quite close. Each image was a composite of several hundred movie frames, stacked in Registax 5.1. For fun (heh, geek fun) I also made a colour version, where I corrected the colour cast, blurred the hue channel and ramped up the saturation.
