Well, I guess with a 1’’ sensor you can’t expect miracles at night.
But if that camera can fly, that there is one big plus to make up for some noise… 
Actually, in my experience RC does a great job with darker areas.
MUCH better than photoscan for example, which was one of the reasons why I looked into it more closely.
Where with PS I got weird bumps in shadowy areas, RC showed a smooth surface.
So I wonder if brightning up the images before processing them in RC is actually neccessary…
