LBN 683 is a reflection nebula in Ursa Major
LBN 683 is a reflection nebula in the constellation Ursa Major . Lynds rated it brightness class 6 of 6, the faintest, and color class 1, the bluest, strongest on the blue print. It spans 5° × 30′ of sky. It is a faint target for long-exposure photography, and it is highest in the evening sky in March.
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.
