This small and dim object appears to be a dim little cloud sitting in the heart of Aquila. There is no hydrogen-alpha that picks up so narrow band filters are not much use. I think larger telescopes will not pick up much structure in this one. The color filters work well but this object is very faint and has a very low surface brightness. I used a synthetic luminance of the RGB but at only 40 percent. The black and white image also has some clear sub-frames added to it.

This appears to be ths same as the high velocity cloud [PDS2002] HIPASS HVC 378 = [DBB2002] 106.
