Comments:  This was a real pleaser with the 300D although the framing could be improved.  NGC6992 is the eastern arc of a system known as the Veil Nebula.  The nebula is also known as the Cygnus Supernova Remnant and Cygnus Loop.  Other parts have the designations NGC6960, 6979, and 6995.  In total, the Veil Nebula is six times the diameter of the full moon.  Despite its overall brightness of about magnitude 5, this object is only visible to the naked eye under exceptionally good viewing conditions because its light is distributed over the object's large size.
