That would be great. Can you post it? If the P900 records GPS co-ordinates in the metadata then could you post that too? (Metadata gets stripped out by the forum software).I specifically said SEA LEVEL because that's where i was at the bottom of the hill on the rocky beach where there is a public trail. I have taken a photo with my Nikon P900, I would be happy to show it to you.
From the curve calculator, Santa Barbara island should only be visible if you are higher than about 100ft above sea level at that distance, barring any unusual refraction effects.
