Description

Sh2-261 (or lower fog) is located between the H-II region, the outer edge of the Milky Way, the boundary between the Orion and the Perseus arm. Although in the northern hemisphere, every inhabited area of ​​the Earth can be observed. The rarely photographed area of ​​the Lower Fog, perhaps due to its visually pale appearance. It is therefore not surprising that this object was first discovered by Harold Lower and Charles in 1939.
