NGC6992, NGC6979, NGC6960, The Cygnus Loop.
This area of the night sky is commonly named the Veil Nebula. It lies south east in the constellation of Cygnus the Swan.
I was using my ten inch reflector piggybacking an Atik 383L mono CCD camera with a 200mm F4 lens. Astronomik filters was placed in front of the lens mounted on a Vixen atlux mount.
I captured 2 minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image.
The total exposure time was 60 minutes using a H Alpha filter, 30 minutes using an O111 filter, 30 minutes using an S11 filter and 6 minutes using a blue filter.
