Ritwika shares how she took solar eclipse photographs at Mount Hamilton California. However she has observed few black moving dot Silhouette against the sun. There was no visible flying aircraft in the sky at that moment. She found no insect or dust on the lens filter, but the moving black object was still visible in her camera LCD display. She has also checked for dead pixel in the sensor, but there was none. You can download the original out of camera pictures at ritwika.com/solar site. Do you have any idea what it was or what might have caused it?
