baader "semi-apo" filter

Apparently Baader has come out with a new filter (see link below) combining the fringe-killer and moon&skyglow specs--the S&T review highly recommended stacking these two, so this is kind of interesting. Anybody look through one?

Don't have the Semi-Apo, but I do use the Fringe Killer with good results on my Stellarvue AT1010 80mm achromat. To give you an example of performance, it reduced the diameter of blue haze around Saturn by a factor of 2 allowing me to snag a close in satellite that was invisible without the filter.
