    Mintron 12V1C-EX and lens 12 mm f/1.4
    field of view 30 x 22 degrees (pixel size 0.04 deg)
    
    The camera was aimed at the midpoint between shadow entry and
    shadow exit for geostationary satellites in Cetus. The Moon was
    97 % lit not far away in Aries.

    Without the Moon Eutelsat W3, Sirius 2 and Express 3A would have been
    visible to the naked eye. I enjoyed seeing Sirius 2 with a 10x50 binocular.
