I'm pretty darn happy with the result.
What's making me the happiest is that I can finally image to my west. Using luminance and RGB filter, the west was just horrid because of the severe light pollution (I'm imaging right over Bellevue, WA, a large city with skyscrapers and all the trimmings). Narrow band really does cut through the light pollution effectively. With these long total exposures, there is some bleed-through, but it's mild and I expect flats to handle it. Even just doing gradient removal in Photoshop, the results are quite good.
