Today I had my last narrowband filter delivered, which completes my SII:Ha:OIII filter set. It's an Astronomik 13nm SII filter, which lets ionized sulphur emission lines at 671.7nm and 673.1nm through. I am going to try tri-color narrowband imaging this fall using my DSLR. I know its a hard task, but at least I am sure it can be done. All my filters are mounted in Gerd Neumann's filter drawer system, which allows me to change filters without unmounting the camera.
