BAADER PLANETARY COLOUR FILTERS 1.25" Collimation the nearly parallel light canThe Baader 1. 25" Colour Planetary eyepiece filters are the finest colour filters for planetary observation available. The transmission efficiency of the three longpass filters (yellow, orange and red) peaks at 98%, while the three bandpass filters (dark blue, bright blue and green) is almost 70%. This is unmatched for simple coloured glass filters. The optical surface of fine optically polished so that there is no loss of sharpness at high
