LBN 992 is a reflection nebula in Orion, 1,410 light-years away
LBN 992 (DG 75) is a reflection nebula in the constellation Orion , 1,410 light-years away. Lynds rated it brightness class 5 of 6, faint, and color class 1, the bluest, strongest on the blue print. It spans 10′ × 5′ of sky, about 4.1 light-years across. It is a faint target for long-exposure photography, and it is highest in the evening sky in February.
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.
