LBN 157 is a reflection nebula in Pegasus
LBN 157 is a reflection nebula in the constellation Pegasus . Lynds rated it brightness class 6 of 6, the faintest, and color class 1, the bluest, strongest on the blue print. It spans 1.5° × 20′ of sky. It is a faint target for long-exposure photography, and it is highest in the evening sky in October.
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.
