     Thanks for that link to images of ISS taken using
    just an 8" scope, 20 cm. This makes it possible the
    shape of that object in question could be resolved
    with an 8".
     Note also that 20", .5 meter, scopes are much more
    common than 1 meter scopes among amateurs. So they
    would provide a much more easily accessible method of
    confirming the shape of the object than by using a 1
    meter.
     Here's a .5 meter binocular scope:
    
    22" binocular.
