North is to the left in this image. This image shows two star clusters, NGC 6755 and NGC 6756 in the constellation of Aquila. They are located in a region where the Milky Way background stars are fairly dense. There is some reddening of these cluster due to intervening galactic dust. The larger cluster toward the lower right is NGC 6755; NGC6756 is the smaller cluster. NGC 6755 is about 4,700 light years distant from Earth while NGC 6756 is about 4,900 light years distant from Earth.   Horizontal FOV is 60'
