    Morning again..
    Thanks for the picture. As you say plenty of trails -- has me a bit puzzled at 
    the moment... Messier 104 is a little bit away from the geobelt ( Messier 104 
    dec  ~ -11 degrees) so any geos seen would have to have some inclination which 
    would give satellite trails at different angles- all yours are at the same angle 
    so that tends to rule out most of them-if not all - as being geosats.
    But the possibility of them being due to dead/hot pixels doesnt exactly fit 
    because these are fixed in the image and will not trail - althoughly possibly 
    you stacked several images on stellar objects so with a bit of drift in your 
    images the stars would register as stellar points and the dead pixels will trail 
    as a result of drift from image to image...
    Ill have a closer look at the image just now and see what geosats were in the 
    area but I think I can safely say you are not going to get many geosats...
