Not really though Canberra has been cloudy in since I got it so I havnt had a chance for a proper shoot. I typically use LiveView (to lock up mirror) the low speed continous shooting mode with a cabled remote where I can lock the shutter button down and the camera reels off 100 shots, then I can reframe and repeat. I pop the lenscap on at the end for darks and do flats in the garage with one of Peter's lightboxes. So I would never alternate in the way you describe and I don't get any problems with using the filter (it will live permanently in the camera, not swapping in/out ever) beyond it obscures the optical viewfinder which I cant use anyway.
I'd be interested to see how the narrowband filter works out too. Finally some love for Nikon
