Sh 2-1

Sh 2-1, also known as Sharpless 1, is the combination of a diffuse HII emission nebula and reflection nebula in the constellation of Scorpius with Pi Scorpii at its center. It appears as a modest brightness making it one of the easier Sharpless catalog objects for amateur astronomers to view. It features an apparent central star^[which?] inside the nebulosity however it is not part its system nor a left over remnant.^{[citation needed]}

Reflection nebula
Sharpless 1 (red emission nebula mixed with the reflection nebula (vdB 99) around Pi Scorpii and LBN 1094 (south of Pi Scorpii). To the east of Sh2-1 are LBN 1092 and LBN 1093.

The nebulous area is fairly large with an irregular shape appearing as a 180° arc shape surrounding a central star.^[3] The remnant^{[clarification needed]} has an apparent diameter that covers approximately 150' and an estimated distance of approximately 650ly away.
