More findings on noise and night shooting.

Went out last night for my second night of night photography. The moon was mostly hidden behind heavy overcast which was frustrating, however I got this shot from the rocks looking back under the moonlight.
Turrimetta Rocks At Night

So a couple of important learnings from my second night out.
Moonlight helps big-time
It looks like I may have been just a tad quick off the mark about the lack of noise reduction. The Long Exposure noise reduction doesn't seem to impact the noise levels in the picture per-se, but Toby and Tim nailed with their comments. It seems the Long Exposure noise reduction doesn't significantly help with overall noise levels, but what it looks like it helps with is "Amp glow".

Check out this shot (you may need to click on it to view it large).

Check out the purple amp glow in the bottom right (very bad) and also in the bottom left.

This shot was a 10min exposure. I went back and looked at my earlier shots to see where it seemed to kick in, and it looks like it kicks in around the 5-6 min mark. Anything under that and I couldn't really notice it, but definitely on the 6 min exposures and 8 min exposures I could see it.
