About images (click on them to see bigger)
This wide field image centered on the summer constellation Scutum shows several dark nebulae, as we are seeing toward the center of our galaxy - the Milky Way.
The bright open cluster on the left side of the image is Messier M11, one of the most remarkable open cluster visible in our sky.
The annotated image allows to identify all the dark nebulae visible on the image: they are identified by the letter B followed by a number, where B means Barnard, from the name of the astronomer who catalogued them.
