The Veil Nebula in Cygnus is the remnant of a supernova that occurred
about 35,000 years ago. We see fragments of an expanding shell of
heated gasses. Of all of the large objects in the sky, the Veil
has the most prominent bluish-green nebulosity due to fluorescence
of ionized oxygen-III.

Move mouse cursor off image to see it anti-vignetted. Note that
the vignetting of this lens at f/2.8 is about the same as other
excellent lenses and scopes I've used at f/5.6 or f/6.7.
