Astrophotography

Both day and night, the sky holds things of interest to me as an amateur astronomer. My two most favorite objects to observe—the Sun and Moon—are surprisingly dynamic, and they continue to draw my interest as a photographer. Other brighter objects beckon me to capture their appearance using my camera.
