Using my Sigma 150-600mm with TC-1401 and the D850 I tried to shoot the Jupiter. All overexposed, too long exposed with 1 second and very tiny which does not make this an option for planet or even star shootings. 850mm on full frame is far too short for such pictures, but, anyway.

If I am not wrong it should be Callisto, Ganymede, Europa, Io (from left to right).
