good filter for MOONLIGHT

[Sreesha74]

is there a filter that filters moon light, and just lets in OII, SII and H-alpha?

i know moonlight is flat with all frequencies, but just checking if there are better experiences?

 

ofcourse I DONT WANT the ambient lights /street lights / sodium vapor lamps as well.

 

some choices, want to get some inputs which is the best and why:

 

altair quadband, optolong L-pro broadband, radiant tri-band & cls nebula filter.

 

Does any of this perform better than rest?  Does it cut the Fullmoon light?

 

Thanks

My experience is that the only filter that cuts down moonlight appreciably is H-Alpha and the narrower the better.  I use an Astrodon 3nm Ha filter but they are very expensive.  Previous I used a 5nm Ha but the 3nm is significantly better.  I also have OIII and SII filters but don't use them when there's a bright moon.
