[N1 (Mirko)]

Apart from visually observing it, I also managed to grab some video of this event. Altitude was low, and the seeing pretty unremarkable (making the moons appear bigger than they are), but you can see what's going on. Dynamic range was a problem (but will be MUCH worse during the Venus-Neptune event 28th), so I made 2 different attempts at showing it in one picture. One a composite from 3 different streams with no object overexposed to give a rough impression of the visual appearance, the other simply a stacked stream that greatly overexposed Jupiter and its brighter moons but showed Neptune much better & Jupiter added back in from the other stack.

An enjoyable morning that one.
Forget Triton though
