I think the 13nm you want would be about as narrow as you can reasonably go, and youll be supprised at the results even with urban skies and moon, its the next best thing to dark skies..

Thanks Fred - that's 2 votes for the 13nm! Keep us posted how you go with the 40D

Yeah Craig probably my dodgy processing - as to removing stars from the Ha hopefully one of the gurus will suggest something but I would try using the Colour Range tool to select the stars then Minimum filter to remove 'em to taste!
Any advance on that
