"Human eye" mode?

One thing I've really enjoyed with Space Engine is the ability to land on a planet and see what the sky would look like from various vantage points in the universe. However, the reality is that the objects rendered are probably way too bright for what the human eye would actually see. Obviously, our eyes do not absorb anywhere near the amount of light as a telescope and thus stars, galaxies, etc. would not look as distinct as they do in SE.

So I'm wondering if it would be possible to add a "human eye" mode where objects' light are limited to what is visible to the naked human eye? That way I could get a pretty close approximation to what a night time sky would look like from, say, a planet in the LMC looking towards the Milky Way.

The default limiting magnitude is 7.0, which approximately the upper human eye limit. As for galaxy and nebula brightness, just change galaxy model brightness to 3.0 (press F7).

I find 2.5 more like what I see on the average night. Exceptional nights can approach 3.5.

You need to base the settings on what you would see from space, since SE already factors in atmospheric extinction on its own. But if the Milky Way's brightness were really in the 3.5-4.0 range then it would have to appear much brighter than it does in photographs. 3.0 matches a bit better. But it's hard to get it perfect, since SE's galaxy rendering, good though it is, is far from realistic.

Wow, you must live in a pretty badly light polluted area. I live in a city of 800000 people and can see to about 3.5 on average nights; a little past 4 on good ones.





I occasionally stream at http://www.twitch.tv/magistermystax. Sometimes SE, sometimes other games.

I was about to say the same thing, but then I realized he was probably talking about milky way brightness, not limiting magnitude.

Man,in place where i live,i can see only 3 stars on the night sky because of the pollution.The main problem is that an Oil Refinery is built side to side with an Chemical Industry which results in yellow pollution clouds....

So sad that i cant see the night sky like in The Australian Outback....





When will our goverments forget about the borders,and start looking into the stars as a species?

2.5 NELM got to be Times Square in New York City smile

I myself have 8 magnitude in SE as default, since there are reports of people seing such dim stars under exceptionally good conditions from Earth, and with the atmosphere removed such stars would be seen much clearer.





Love SpaceEngine!

I'm definitely with you. Your idea inspired me for a more universally useful suggestion





You are now breathing manually..

I can only see about 0.5 at a VERY VERY bright night. I'm just hoping I can see the full night sky once in my lifetime.

I also live in a populated area where I only get a few dozen stars and planets at night.
However - I have been to Hawaii, where stringent regulations keep the light pollution to a minimum, and DANG. I knew that many stars were out there, but I didn't realize just how many we should be able to see down here. There I easily got up to magnitude 7. Still, I tend to keep SE at up to 5 to keep my FPS nice and high.

This would be really cool; I'm always interested to see what it would REALLY look like from a certain position on a planet.
