OBJECT DESCRIPTION AND IMAGE SESSION
Barnard 263 can only be seen because its gas and dust blocks the populated star field of our Milky Way center. The nebula can be found bit south from the imaginary line formed between theta and eta scorpii in the tail of the scorpion. It has an irregular shape. Edward Emerson Barnard was an American astronomer (1857 - 1923). He catalogued dark nebulas objects and his list covers 370 objects. Most of his work was done by taking photographs of the Milky Way. His best know discovery was the Barnard Star in 1916.
