How many times have we heard, "Once in a blue moon?" This image was taken on the evening of a blue moon .The only time you might see a real blue moon is if there are smoke or dust particles in the atmosphere. This has happened when we have had forest fires or volcanic eruptions. I decided the odds would not with me if I waited to see one so I created my own blue moon. I used a filter to color the moon blue. Most of the time when we have a blue moon, it will be full and look like any other full moon.
