Comments:  This is another reshoot of the NGC6992. This time I used the Orion ED80 (a great little scope) on the ATLAS EQ mount and the Hap Griffin modified 350XT. Not a bad combination.  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.
