Cracking - how can we see your documentary?!?! Does it explain how you get such pin sharp stars with (what must be) a pretty long exposure? Or is it just very high ISO with good noise reduction?
Wildeybeast, the documentary I have mentioned before will be available also via UKC! I am super busy preparing my talk for an upcoming Photokina and putting a short "visual story" about my photography. However, I promise I will address the issues of exposure times and sensitivity and each photo will have its settings, so things should be clear!
