Glen ,
There are many different color filters for astrophotography. I contacted with Lumicon and they said their filters were for clearing the night skies or special for nebulas etc.
I wrote to above mentioned british company and asked for a chart for remote sensing filters.
Loris Medici should know that is it illegal or legal to import IR film to Turkey ?
Do these films sensitive to xray machines. I guess airport detectors uses ultrawideband systems ? How can seller protect them when exporting ?
I will post the chart when I recieved. By this way , everyone could select his filter.
I read somewhere someone uses 22 filters for archeology.
And canon ef lenses have very big diameter and it makes filters 3 times expensive than elmar.
