With the “small” telescopes in our school lab, remarkable images are possible. One example is the “Elephant’s Trunk”, an emission nebula in the open star cluster IC 1396 about 2.400 lightyears away in the constellation of Kepheus. Our team member Peter Stinner photographed the nebula for 25 minutes in the light of hydrogen and 20 minutes in the light of double ionized oxygen. The telescope is an ED-APO of only about 7cm aperture, and this in moonlight.
