I have been posting lots of screenshots in this forum since I bought a PJ. Perhaps I am one of the happy kind pleased with the PJ and hence only post screenshots.
I always use a night shot mode with no flash and timer to reduce camera shake. With low ISO you get a smooth image but you will also get blooming or white crush unless the shutter speed is appropriate.
With high ISO you can get a sharp pic but with noise.
Full manual may give you exactly what you see but you need some skills to get the right exposure and shutter speed for each image.
I normally turn exposure 1 or 2 level down to reduce the blooming on my 4 yr old camera but what i miss out is some detail. If the same shot is overexposed it reveals what the PJ is displaying but the pic becomes too bright and washed out...
One thing very tricky is to pick up the right colour as it will depend on your camera and not what you see. Like my camera adds a pinkish tinge and sometimes goes crazy with some shades of blue and violet.
I think we need a screenshots thread so that ppl can post screenshots if they like for fun.
I have added some samples here.
The last two ones actually show more stars if an overexposed image is taken. But I reduce the exposure to get rid of blooming on the primary object.
