OBJECT DESCRIPTION AND IMAGE SESSION

Just half degree to the south west of Messier 24 we found this colorful complex area of where a great variety of objects are displayed in a 34 arc minutes field of view. IC 1283, 1284 and 4700 are the H2 clouds which absorbs the radiation of nearby stars and release it a red light. The two bright blue clouds are NGC 6589 and 6590 which appears to be superimposed and merged with the H2 area mentioned. Finally NGC 6595 is a loose open cluster interacting with the reflexion and emission nebulas.
