About this image

This SNR is the brightest radio source in the sky. The explosion should have been visible circa 1690 but there are no written records. It is seen here as a colourful ring of material about 10 light years in diameter lying at a distance of 11,000 lightyears. I think an an L-enhance filter would bring out the fainter detail.
