Astrophotography

Steve Mandel's interest in astronomy began when he was 11 years old. He built his first telescope, a 6" reflector, at his home in Los Angeles. His interest in
astrophotography Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon) was taken in 1839, but it was no ...

, where about 250 amateur astronomers and manufacturers of astronomical equipment and software meet annually to discuss technology, imaging techniques and possibilities of scientific contributions. He created the so-called Hubble Award, given at the conference to an astronomer who made significant contributions to astrophotography.


Wildlife

Besides astrophotography Steve Mandel has captured and published also images of endangered animals. He specializes in using robotic devices to gain artistic wildlife photographs from unusual angles.
