Sh 2-41 is a large nebula in Sagittarius and a component of the Small Sagittarius Star Cloud[5] Sh 2-41 appears near the northern edge of the star cloud.
Sh 2-41 contains multiple smaller components itself. Another Sharpless object, Sh 2-39, is contained within. Sh 2-39 itself contains potential infrared cluster [BDS2003] 6.[6] Dark nebulae Barnard 92 and Barnard 93 are both located within Sh 2-41. These areas are regions of intense star formation.[7] Open cluster Collinder 469 is located just south of Barnard 92, and open cluster Markarian 38 is located just to the south of Barnard 93.[8]
