    shot of 1,6W projecting at a hill above our town, you can see the blue in this one is quite dominating



    and here is the spot, you can see at 2,5 km distance it starts to be a bit misaligned

    Wow, beam seems to have a very small divergence! Are you sure it's really 2.5km far away? According to its 0.8 mrad divergence (what I have measured if I remember), beam diameter should be around 2 meters at 2.5km... Maybe the picture is misleading me and the beam is bigger than it appear I don't know.

    according google earth it was 2,51 km exactly from the balcony with projector to pile of wood on the hill, the inner beam that is white was quite small but separate beams seem to be bigger with blue making a line shape

    Divergence is really really small.
    Beamspecs are stunning.

    I'm using a kvant for my graphics, despite not having chosen for the CT scanners and having LM scanners (which are still good). I'm using this thing for graphics and the colors are beautifull.
