Hi again George,
I've done some investigation with an optics related newsgroup, and they suggest that, at night, with normal vision, a 4 minute of arc seperation of light is "about right". For a ship ten miles away, this is about 70 feet. So, from the Californian's point of view, all the deck lights would have merged into one glow - apart from this, the only distinguishable light would be the red sidelight and the mastlight.

Coupled with the apparent size of the ship (because she was not broadside on), no wonder Gibson and Stone thought that they were seeing a relatively small ship!

Best wishes

Paul

Hi, Paul!

Thanks for the extra info! It's good to have this kind of information quantified to a specific figure.

All my best,

George
