The cluster of Sharpless objects is also located where the galactic center of the galaxy is located. In this image it is located in the upper right corner of the image. Sharpless 19 is in the middle of the image while Sh2-18 is the smaller one to the lower right. In the lower right from Sh2-18 is Sh2-16. The upper left of the image is where Sh2-20 is located leaving Sh2-17 in the upper right. This area is rich in hydrogen alpha so a nice long exposure will pick up nice contrast. Most of the region is mostly red so getting a HA-RGB color image is fairly easy.

This nebula is part of the Sh 2-15 to Sh 2-20 complex of HII regions located in the Sgr OB5 association in the Sagittarius arm. It contains the infrared star clusters [DB2000] 5 and [DB2000] 6.

Avedisova includes Sh 2-20 in her star formation region SFR 0.33-0.19 along with a methanol maser and the radio source Seiradakis 36
