Perseid meteor shower over Ricardo Breceda sculptures; Borrego Springs; August 13, 2015
Photos in this gallery were taken at night, using long exposure with a tripod-mounted camera. Light sources usually involved a mix of natural light (moon, starlight, residual twighlight) supplemented by 'lightpainting', using a hand-held flashlight to 'paint in' selected features. Visit the NOCTURNES website for more information and examples of this technique.
Total solar eclipse of August 21st 2017, viewed from Oregon
Annular solar eclipse of October 14, 2023 from northern Nevada
An interesting aspect of an annular eclipse is the appearance of Baily’s beads. These are beads of sunlight either disappearing or reappearing through deep lunar valleys along the limb of the Moon. Although Baily’s beads can be seen at the centerline of the eclipse path, they appear for only for a few seconds. In contrast, at the edge of the path is it possible to see the beads speed up and slow down for a few minutes before and after peak obscuration. This is the so-called “grazing zone”. Whereas eclipse maps show straight lines representing the edges of a path, it is actually an irregular shape defined by the Moon's bumpy terrain. High-resolution data from NASA’s Lunar Reconnaissance Orbiter (LRO) now make it possible to plot the “grazing zone” on Earth, a region roughly 3 km wide. I used Xavier Jubier’s wonderful interactive Google eclipse maps to select a location in the Black Rock desert about 3 miles north of Fly Gyser,. a site I had long wanted to photograph and which was conveniently accessible later on the same day through a tour organized by the Friends of the Black Rock Desert. The eclipse would peak at 9.31 am, but the prospects of seeing it seemed poor when we crawled out from our tent at dawn to find the sky completely overcast with dark clouds. Over a few hours, however, the clouds started to thin. With only ten minutes to go we began to make out the largely eclipsed sun through the cloud, and a patch of blue sky drifted in the right direction to give a clear view at exactly the right time.
