Comments: this is a very faint target, much more than I thought before imaging it.
The Aquila constellation lies a few degrees North of the celestial equator. The alpha star, Altair, is a vertex of the Summer Triangle asterism, near of it the Aquila Rift is found at and estimated distance of 600 light-years from the earth. Its dusty molecular clouds contain raw material to form new stars. This close-up looks toward the region at a fragmented Aquila dark cloud complex identified as LDN 673 on the right and at another more homogeneous dark cloud complex identified as LDN 684 on the left of the image.
