Past summer I was able to shoot S2 data and combine it with previously captured Ha and O3.

The Veil Nebula is part of the Cygnus Loop which comprises several NGC objects. Shown here is NGC 6992 in the Eastern Veil. The Veil Nebula is a faint supernova remnant that exploded some 5000 years ago, and since then it has been expanding on the sky to cover some 3 degrees. Its fine and intricated filaments are attributed to a thin shock wave propagating into space and seen edge-on.
