You want as much signal as possible so the filter should have the highest transmission possible with a wide spectral bandpass. This combination provides the greatest sensitivity and gives you the highest photon counts on your pixels. While the high transmission level is a great aspect of the new Astronomik Luminance filters, not all optical instruments or additional optical
