Question
I've been taking a few shots of the Milky Way using my 16-35mm lens @ f2.8 ISO2000 and 30 secs exposure. I'm getting okay shots, but nothing great - not really sharp and lacking in colour.
Is there a filter I need to use to block out light pollution from nereby cities or do I simply need to adjust my camera settings?
Question
How important is it to calibrate your lenses to your DSLR, especially if they are third party lenses?

Question
How do you know when you've got the correct colour balance in post-production (i.e lightroom)? To explain further, I have several shots where the same rocks or stones are grey in one shot and brown in others. Similar comment for sunrise photos with red/orange hues.
