Description

At a distance of 10,000 light years and an approximate diameter of 98 light years, this is a massive distant and very faint object. With 20 hours of data some good detail and color finally emerged. The Ha signal is quite strong, but the O3 filament along one edge of the shock front was extremely faint.
