Re: Question about a satellite I may have imaged

Im not a experienced expert but my 2 cents

I think is big for a Satellite, but perhaps is a visual effect and someone
has more info. The ISS transits photos I ve seen are smaller than the
photos you atached , and probably ISS is the biggest satellites in terms of
apparent size.

It seems in fact some out of focus near-object like a BUG... What do you
think?
