All rigth... start from scratch.
The moon ligth isnt blueish as i tough has a temprature of 4100-4150 a rather yelowish tone. And thanks to this
http://en.wikipedia.org/wiki/Purkinje_effect we perceive as blueish. So i put the Corona sun as 4150 Kelvin Temp.
Respect to relative brightness to dayligth, using this info
http://en.wikipedia.org/wiki/Daylight i use 1/1000 as Intensity on the sun.
I-m lost respect the size of the moon respect of the size of Corona Sky but as i intend to apply photoshop on the disc i leave as 5 for now.
I never knew that where a setting like bitmap paging in max and by default where active. If you wish to wait for your renders forever leave this on. See this as reference
http://jokermartini.com/2013/11/14/render-speed-increase/.Thanks to suggest that.
Using a default Corona material override, in post settings in corona use 4150 as white balance as the predominant ligth source was the moon. Giving me a yelowish tone. But just as stated before our eyes shift that illumination to blue so i try a value of 3150 to return to that blueish color.
For the lamps i put corona sphere 3000 Kelvin for simulating tungsten ligth. This link explains a little about moonligth photography
http://www.cast-lighting.com/search/1/display-document/71I try an spherical star map as suggested in the forum but it turns out that the stars renders too big and unnatural.
This is the link for that realistic position and brigthness star field
