This image shows you two paralleling small globulars at 0.5 degrees northwest of gamma Sgr.
Right (west) and left (east) ones has numbers of NGC6522 and NGC6528, and visual diameters of about 9 and 5 arc minutes, respectively,
NGC6522 has about two times larger size than NGC6528.
And you can see an indistinct dark nebula of B298 just southeast of NGC6528.
