I moonless night presented so it was a great opportunity to take on my first dark nebula. I managed 5.6 hrs of integration (180 sec subs) at gain 140, with a sensor temp -10C. I see the seahorse, but I've lived in Japan off and on since 1974 so this also looks like a satellite image of Japan to me.
