Whole field was full of nebulosity. The nebula has five different parts and several brightenings. In the middle of nebula there is a huge dark lagoon which strolls trough the brightest parts of the main-nebula. Open cluster NGC 6530 is quite strange; stars lies almost systematic in same lines and columns.
