Barnard’s E has to be one of amateur astronomers’ all-time favorite binocular objects. This combination of two dark nebulae (Barnard 142 and Barnard 143) comes from American astronomer Edward Emerson Barnard’s catalog of such objects.
The E lies against the rich Milky Way in Aquila. Start at yellow-hued magnitude 2.7 Tarazed (Gamma [Γ] Aquilae). If you center Tarazed, you shouldn’t have to move your binoculars at all. Barnard’s E lies 1.6° west-northwest
