IC 5146 "Cocoon Nebula"
    Constellation:  Cygnus

    Size: 9 arcmin

    Magnitude: 7.2

    RA:  21h 53m 30s

    Dec: +47 d 16m 0s

IC 5146 is a large object with low surface brightness.  It should be difficult to see in amateur scopes.   I don't know for certain, because I did not try to see it visually when I took these images.  All together four 20 minute guided exposures were needed to clearly show structure of the nebula and display good color saturation.
