LBN 409 is a reflection nebula in Cygnus, 2,020 light-years away
LBN 409 (DG 169) is a reflection nebula in the constellation Cygnus , 2,020 light-years away. Lynds rated it brightness class 3 of 6, moderately bright, and color class 1, the bluest, strongest on the blue print. It spans 2′ of sky, about 1.2 light-years across. It is a telescope object under a dark sky, and it is highest in the evening sky in September.
Reflection nebula: a cloud of dust lit by a nearby star. The dust scatters blue light best, so reflection nebulae look blue in photographs, and a nebula filter does not help them.
