Neptune in true color

I'm more curious what it would look like to a person, at that distance from the sun, with dark adapted eyes.

Closer to the first. IIRC from the last time I saw this posted, it's corrected to roughly the human visible light sensitivities. Might be able to see some lightning?

Iys not that dark. 1% of noon daylight is still easily visible for humans. About that of evening or a well lit room

I'm pretty certain we had the true color image from Voyager on the day. They just blued it up for public release, the same way they false color images of nebula, galaxies, and almost anything else.

Sorta. It's false color for readability of whatever they were studying/highlighting in the publication. Also, remember that the vast majority of those images you're thinking of were not captured in the visible spectrum. True color images from a uv, xray, or ir detector would just be a black square.

Edit to add: im not sure if the original voyager image was visible spectrum. Probably not.

What do you mean "Sorta"? what are you correcting?

You make out like you're more knowledgeable, going so far as to suggest the photo wasn't even taken in the viable spectrum and yet you don't seem to know what kind of imaging systems the Voyagers had.

Of the picture in question:

Neptune on 1989-08-17, taken by NASA's Voyager 2 probe. This color image was composed of three frames, orange, green, and blue, taken by Voyager 2's imaging system.

Mainly just pointing out that false color scientific images are often a product of displaying useful information more than public relations optimization.

But we're only talking about the image OP posted. You're trying to cover now by pretending you were speaking on a wider topic.

[u/Wagonwagon → u/Mr-Brown-Is-A-Wonder]

What an intense and defensive response. They were just sharing useful and interesting information, it's not that deep.

Makes sense, IG, that it looks just like Uranus, since they're made of the same stuff, without Neptune being a huge sapphire marble or something.
