The O-III signal is weak. After some extreme stretching of the data
there was plenty of it after all. I have not noticed before how far it continues
outside of the Hydrogen alpha area. O-III can be now seen at seven a
clock from the main formation and some faint areas in upper left corner with H-alpha.
