I did have a chance to try the unit out in my LX90 last night. Simply Amazing! I don't think I can ever go back to monocular viewing! And the binoviewer itself is a work of art. I am extremely impressed. I had my best look yet at Comet Holmes in reduction mode of the Power x Switch.-R. Harris 11-15-07
