M 42 The Orion Nebula and Neighbors

The celestial region shown in the image comprises the surroundings of the Large Orion Nebula. Most of the objects visible in the photographs are located in the Orion arm of the Milky Way, as is our home solar system.

Tadpoles in the Cosmic Pond: IC 410 and NGC 1893

In the constellation Auriga on clear winter nights one can find the open cluster NGC 1893 embedded in the emission nebula IC 410. While NGC 1893 can be observed visually using a telescope with proper aperture the faint nebula IC 410 is a real hard case for the visual observer and much easier to catch by photography. Due to some smaller but prominent star formation regions the nebula IC 410 is nicknamed as the "tadpole nebula". IC 410 was discovered on September 25, 1892 by the (german) astronomer Max Wolf (June 21, 1863 - October 3, 1932) while the open cluster NGC 1893 was discovered already earlier on January 22, 1827 by the (british) astronomer John Herschel (Mar 7, 1792 - May 11, 1871).

What can be seen in the image is what cannot be seen visually through a telescope. The image is presented in false colors resulting from an (amongst astro-photographers widely known) image acquisition technique using narrow band filters.
