I have read various threads with different opinion but at the end a set of unused 50mm square Baader filters were just too good to pass for my new CCD.

Unfortunately cloud rolled in to complete RGB but i don't see any halo even on Alnitak through Lum. See attached 300% crop on some bright stars through FSQ106N +PL16803 combo and 5x 5min subs.

I know some of you have gone through Baader filters and had halo issue. So my question is when you had halo issue was it through R,G,B or did the Lum give halo as well?
