Barry,
Estimated SNR weightings for the integrated masters were 97.4 (Ha), 17.9 (Oiii) and 44.4 (Sii.) So, there was a fair amount of Sii and not so much Oiii.
Just for giggles I worked out that per pixel I was detecting 0.63 photons/sec in Ha, 0.13 p/s in Oiii and 0.35 p/s in Sii in one of the brighter blue areas. It is definitely a dim nebula.
Cheers,
Rick.
