Baader 2" Colour Filter Set for Moon and Planetary
Baader 2" Color Filter Set comes in 6 colours for contrast enhancement for lunar and planetary observations. It includes three bandpass filters (Green, Bright Blue & Dark Blue) and three long-pass filters (Red, Orange, Yellow) to be fitted to 2" eyepieces. The filters are carefully designed with spectral characteristics. They may be stacked without image degradation or ghosting, in order to provide even narrower passbands. You can even combine it with any of the other Baader filters for interesting possibilities.
The Phantom Group Coating developed by Baader Planetarium is a 7-layer broadband coating with extremely low residual reflection. The term "Group" indicates that the respective most effective anti-reflection layer system was calculated for each type of glass of the filter.
