NG6960 - Western Veil (H-alpha)

20:57 9/8/2007 UTC

I started a little project on narrowband Veil Nebula. First image is 2 hours worth of H-alpha featuring Western Veil and Pickering's Triangle. Next clear night I try to shoot the exact same location with OIII filter. The goal is to shoot 2h with three narrowband filters.
