Hi All,
Tried out a Baader Contrast Filter + a UV/IR Filter on the Canon EOS300D (modded) last night on M42, results herewith, I dont think it does much for this subject and the colours are changed also, The blue nebulosity is tinted brown (the Filter Colour) however ill try a CWB through the Filter and see what this does for it all.
