Marv, As I recall the Focuspot, the light source sat on the top end of the vertically mounted RF and shone its light through a little transparent port directly along the axis of the RF. Because of the beam-splitter mirror, half of the light emerged from the top window of the RF, half through the bottom window. When the camera was focused, the two beams converged on the subject. If you are putting your laser light source in the same location, then how is there any danger of light coming out the eyepiece? RKS
