Let me explain how I got 20sec on the geola Web site has a calculator and when I ran it for red and green I found out that the red need a 20sec longer exposer , so I used a piece of black paper to block green laser in the unit. The 640nm only has transmission of 15% and 532nm green 50%

Very nice. Did you use simultaneous illumination of both wavelengths or sequential?
