I tried using just the Nikon RAW (NEF) format tonight with my D5100. When I tried my first Blind Solve it couldn’t locate the image. I checked the image location in the temp files and the image was all black. I tried numerous times with different exposure times but got the same result. I then changed to using FITS files and everything worked fine. I was going to check later if the NEF files would work (download) when running sequencies but the clouds rolled in.
