"The front end filter can be employed as a means to enhance contrast for poor lunar lighting conditions or for
spectral analysis using standardized color filters. By using a R60 red filter, the detrimental effects of 
bright moon lit nights can be minimized by enhancing the meteor's most detectable spectral region in the near

Probably, you are both correct.  You are talking about the majority of energy being in the blue and
UV range and he is talking about the spectral region most detectable by low light CCD cameras.  My
original statement might have been better as "where meteors really shine for CCD cameras."
