I wouldn't bother with a M+SG Baader filter either...I know as I have one. All it does is dim everything slightly. I keep it to combine with a Baader Fringe Killer to make a Semi APO filter...with a bit more light through put than the standard Baader Semi APO filter...had one of those too.
Total number of times I have the M+SG and FK combo with my 6" f12 Istar Refractor in the last two and a half years....zero.
