This Blue Moon from November 21, 2010 was photographed in Brooklyn using a Canon 40D and Celestron NexStar 4SE telescope, showing how different white balance settings reveal natural lunar colors.

A blue moon can refer to the third full moon in a season with four full moons. The earliest recorded English usage of the term "blue moon" was in a 1528. In 2010 Blue Moon was November 21.
Equipment Used
- Canon EOS 40D DSLR
- Celestron NexStar 4SE Telescope
Color-Enhanced Blue Moon
1. Neutralize the colors (the median of the values of R, G and B is the same).
2. Create two duplicated layers.
3. First layer set as luminosity
4. Saturate the second layer.
5. Make invisible main background layer.
6. Play games with best parameters
So those colors are real, and the only difference is that they've been exaggerated a bit :)

This Blue Moon project remains one of my favorite lunar imaging sessions. Using simple backyard equipment, the Celestron 4SE and Canon 40D can reveal a surprising range of natural lunar colors through different white balance settings.
