By definition your first shot would be your best shot
(I would tell my only daughter that she is my best daughter. After some years she said - "Wait a minute??......., you don't have any more daughters!" To which I would then reply - yes, you are also my worst daughter.)
But that is a great start. Mine was an overexposed white blob......and I haven't progressed much beyond that!
Well done, Franck! Let's see some more. You should be able to get some nice shadow transits with your resolution.
