Astrophoto: The Gorgeous Colors of a Setting Quarter Moon

When I looked out my south-facing window last night, I saw a gorgeous quarter Moon high in the sky. Giuseppe Petricca from Marina di Pisa, Tuscany, Italy took a longer look and created this beautiful composition of five different shots of the Moon on July 15, 2013, revealing how the appearance of the Moon changes as it sinks lower in the sky.

“These are the colours that our natural satellite assumes thanks to the Rayleigh Scattering in Earth’s atmosphere,” Guiseppe said via email. He noted that in his image, colors of the single shots are not digitally altered (except with a light Sharpness Mask to enhance the surface details.)

Guiseppe used a Nikon P90 bridge digital camera, at ISO 100, and used various but limited exposition times (trying to maintain a short medium exposition range in seconds, he said. His mosaic composed with Photoshop.
