Sharpless 84 (LBN 131 and others) is a HII area possibly ionized by a Wolf-Rayet star (WR 128, HD 187282, HIP 97456 and others). The nondescript star is below and to the right of the brightest part of the nebula.

* del Sge (HIP 97365) is the bright star near the center on the right. This one actually has a van den Bergh designation (vdB 127) but doesn’t appear to have any nebulosity.
