Artist's Description

Featured on RB’s homepage March 22, 2011, along with seven spectacular images.

The first quarter Moon of January 2010 was a beauty. The atmosphere was cloudless, and the air column was as stable as I’ve seen through a telescope. In the 40 minutes allotted, the Moon transited the meridian at 81 degrees above the horizon, where the atmosphere is nearly most transparent.

I used a 2" T-adapter to connect my D90 to the Highland Road Park Observatory’s 20" OGS Ritchey Chretien’ telescope. If the lunar geography looks a bit strange, it’s the result of the scope’s optics rendering a mirror image of what the unaided eye sees. The dark lunar seas at bottom right are actually located at top right and arch downward.

The exposure is 1/60 sec. at ISO 400. All post-processing was performed in Adobe Lightroom 2.7.
