M8, the Lagoon Nebula, is a large emission nebula
containing a number of interesting features. It includes the bright "young" stars of open cluster NGC 6530.
It also contains a number of dark nebulae called "globules". The brightest part of the nebula (seen to the right) gets
the name "Hourglass Nebula" as well. This object is quite photogenic. It often appears together with M20
(Trifid Nebula) or in wide swaths of Milky Way starfield. Its full extent is about three times the apparent size of
the full moon. The new H9C camera has a large enough chip to capture the brightest portions (88
x 65 light-years). The new IDAS filter defeated the skyglow well. M8 doesn't rise very high
in the Harahan sky.
