Veil Nebula in OIII

A narrowband filter such as an Oxygen III (OIII) filter inserted along the optical train lets the light from the nebula (and the stars) pass through, but block out everything else, particularly light pollution. This image was taken in Quezon City with a Canon 450D and a 4 inch f/9 refractor, exposed for 30 minutes at ISO 1600, tracked and guided.
