Description

The "E" or "Barnard's E" Nebula (officially designated as Barnard 142 and 143) is a pair of dark nebula in the Aquila constellation. It is a well-defined dark area on a background of Milky Way consisting of countless stars of all magnitudes. Its size is about that of the full moon, or roughly 0.5 degrees, and its distance from earth is estimated at about 2,000 light years [Wikipedia]. This is a short 3.2hr LRGB image (3.7hr effective with synthetic Lum) in a very dense region of the Milky Way with high contrast for B143 (above) and B142 (below) (North up).

3.2 hour LRGB taken at D.A.R.C. Observatory, Mercey Hot Springs, CA , 6/29/19.
