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.

NGC 225 - Open Cluster in Constellation Cassiopeia

NGC 225 is an open cluster in the constellation Cassiopeia. It is located roughly 2,200 light-years from Earth. It is about 100 to 150 million years old. The binary fraction, or the fraction of stars that are multiple stars, is 0.52. It is also known as sailboat cluster. But what's happening at the top of the mast? The boat is obviously being boarded by an octopus - the more clearer, the longer you expose (or if you drink too much red wine)... Beside the quite nice, probably not so well known star cluster you can see interesting dust clouds and a reflection nebula, which are cataloged as LDN 1291 and LBN 604.

The Iris Nebula NGC 7023

The Iris nebula is a bright reflecion nebula in the constellation Cepheus. It's appearance is caused by the very hot star HD 200775 in it's centre whose light is partly reflected and partly absorbed by surrounding dust clouds. As can be seen from the labeled image, the dust cloud itself can be found in Lynd's cataologue of dark nebulae as entry LDN 1174. The reflection nebula shines at magnitude +6.8. It lies 1,300 light-years away and is six light-years across
