At first glance this image appears to be set with a nearly white background hue. However, the sky seen at upper right is nearly black and it is the extremely high density of stars which is present in this field which is brilliant. M7 is nearly drowned out by the intense Milky Way stars here, so dense is the star field that there is a background unresolved glow over much of the field of millions of background stars. While Barnard 273 is to the upper right, at the left top we seen the scattered dark nebula Barnard 292. This is the deepest exposure of M7 I have to date. The superb contrast of the Supra 400 combined with its low reciprocity makes it ideal for imaging star clouds in our Galaxy.
