2015 Blood Moon

2015 Blood Moon

The Moon near total eclipse glows orange, which is known as a blood moon. This eclipse on September 27 was both a full eclipse and a supermoon, which occurs when the Moon is at perigee in its orbit around Earth. The combination is rare and hasn't occurred since 1982. The next such occurrence won't be until 2033.

I was lucky that I was in Austin for the event, and the skies happened to clear as the Moon started to change color. Back in Houston, the skies were completely cloudy. I was looking for a location where other people were viewing and the skies might be a little less susceptible to light pollution. The little observatory at Southwestern University in Georgetown was one such place, so I took a chance on good viewing and drove up there. I wasn't particularly interested in viewing the eclipse through the telescope, but I figured that I wasn't likely to be hassled if I was with a group of stargazers.

I set up my camera and tripod in a parking lot away from everyone and started experimenting with exposure and focus. This was my first attempt at photographing the moon, and I had done a little reading in preparation. I used manual focus, aided by magnified view in LiveView and manual exposure settings. I had to kick up the ISO setting, of course, to have any hope of capturing a still image.
