Slide your telescope just east of the Lagoon Nebula to find this
alluring field of view
in the rich starfields of the constellation
Sagittarius toward the central Milky Way.
Of course the Lagoon nebula is also known as M8, the eighth object
listed in
Charles Messier's
famous catalog of bright nebulae and star clusters.
Close on the sky
but slightly fainter than M8,
this complex of nebulae was left out of Messier's list though.
It contains obscuring dust, striking red emission
and blue reflection nebulae of star-forming region
NGC 6559 at right.
Like M8, NGC 6559 is located about 5,000 light-years away
along the edge of a large molecular cloud.
At that distance,
this telescopic frame nearly 3 full moons wide
would span about 130 light-years.
