NGC 6871, a loose open cluster containing the Wolf-Rayet star WR133.

WR133 is located just above the center of the image below.

South of the Tulip nebula (Sh2-101), one can also see Sh2-100 (left) and Sh2-99 (right) near the bottom of the image. Also, the planetary nebula StDr 103 stands out very nicely just south of Sh2-101. Further south, just north of Sh2-100 and Sh2-99, one can see the bright part of the SNR 70.5+1.9.
