NII is interesting, but my own experiments with 3nm filters indicate that they are not the optimal choice for f/3 systems. Significant reduction in filter transmission. Still, there are gigs of signal in Bert's image that makes processing quite easy. 50% res like this does not readily show some star problems in the corners. I'll have to go back and shoot this with my FSQ and 5nm Ha filter
Here is the image, enjoy:
