Sh 2-37, also known by the designationIC 1284, or the common nameTwiddlebug Nebula,[5] is anemission nebula in the constellationSagittarius. It is located is the direction of ionizing star cluster Dias 5. It also contains the radio source W 34.[6]
It is located near the center of the galaxy, and is partially obscured by dust. Nearby Sh 2-37, which appears mostly red, are two small bluereflection nebulae, known asNGC 6589 andNGC 6590.[7][8]SIMBAD notably provides the wrong coordinates for Sh 2-37, giving it the same coordinates as nearby NGC 6590.[9]
Sh 2-37 was discovered byEdward Emerson Barnard on a photographic plate on 31 May 1892. He initially described it as a 'nebulous star'.[10]
