A Swatch of Veil - NGC 6995 (August 2014)

Full resolution image here.

Of course, this is part of the Veil Nebula, a supernova remnant in Cygnus.  This is just the Ha (and perhaps a bit of NII).  I've wondered whether the arcs help show the location of the original blast (relative to what remains).
