RR, liked your astrophoto. I know what Sagitarius looks like but I couldn't pick it out. Just a sense that I know that patch of sky.

Thanks! That's my point. An easy constellation we might be able to spot in a second on land becomes impossible to find at sea hundreds of miles from any light. I've heard stories from astronomers who observed an eclipse from Ayers Rock in Australia that the Milky Way cast a shadow there! Imagine: something most people who live in a city have never seen so bright it casts a shadow!
I'm afraid the sky at sea would look very different from what we see in SH4 and the more we know about the sky the less we would recognize it. As the sky gets darker and clearer away from land the star colors become much more apparent, especially the red giants, which are suddenly easy to spot everywhere! Another thing that happens when there is no light pollution and the air is very clear is that the stars look much more the same brightness. It is difficult to separate a 2nd magnitude star from a 4th magnitude star, even though one is four times brighter than the other. And you see literally thousands of stars so dim that you've never seen them before. That makes it difficult to pick out the constellations that are outside of the Milky Way too. It's a humbling but wonderful experience if you're supposed to know the sky.
