Is there anyway you can screw the OIII and SII on the nosepiece of the filter wheel somehow? You're usually collecting LOTS or long subs for NB, so the extra screwing on and focusing is less of an issue. Pretty much a night on each filter (or at least 1/2 a night) for those to get decent signal. If you went this way would select L filter for filterwheel with the single NB filter on the nose.
