Copper Moon over a Copper Mine


Copper Moon over Copper Mine

A coppery Moon rises over the Santa Rita Copper Mine. 

The March 5 Full Moon was the smallest Full Moon of 2015, the “apogee” Moon. Or call it the March mini-Moon.

I captured it rising over the vast Santa Rita Mine, east of Silver City, New Mexico, my winter home this year. The Santa Rita mine is one of the oldest continuously operating mines in western North America. I shot the scene from a viewpoint west of the city, using a 135mm telephoto lens.

The image is a composite stack of two exposures taken moments apart: a long 1-second exposure for the sky and ground (but with the Moon overexposed) and a short 1/13-second exposure for the lunar disk to retain details in the disk, like the lunar mare, marking the face of the “man in the Moon.”

The March Mini-Moon

Later in the evening I used my telescope to shoot a close-up of the apogee Moon. I shot a single exposure but processed it with exaggerated vibrance, saturation and contrast to bring out the subtle colour differences in the lunar mare. You can see that some are much bluer than others, due to the higher level of titanium in the lava flows that formed these mare.

As I explained in my previous blog, in seven months the Full Moon will be at the close perigee point in the Moon’s orbit, giving us the closest Full Moon of 2015. That’s also the night of a total eclipse of the Moon. I’ll try to shoot the Full Moon with the same telescope to create a big and small Moon comparison pair.
