This is two shots stitched in Lightroom. I never use the in camera stuff. Here's another pano from the south end of our island where the Stikine River meets the sea:
Nice shot! Is this where you live? Very lucky.
What I have started doing is if I hold my fist at arms length that angle of view across the fist is roughly the 168mm so the best I'm going to get is a single 168mm photo if it's wider than that...
I think at 10%, it's time to come home.
I don't trust the readings on the batteries as the usage is based on current power consumption and returning to home can take more than current.
