    Description

    Hi,

    I began this project during this summer.
    I've first made a 3 tiles mosaic in cygnus with my A7s, Samyang 135 and STC duo narrowband filter (you can see it in a previous picture).
    Now I've had 5 more tiles.
    For each tile : 155 x 30 sec at 3200 ISO, lens at f2.
    This picture is 70% from original.

    The processing is 100% done with PixInsight.
    The result is not perfect (some merging artifact are remaining) and the color rendering may not be to everyone's taste, but I'm quite satisfied.
    It's a long and tough work to create such mosaic.
    I hope you like it.

    CS, David.
