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
