I believe you're on max 10X zoom when taking those night shots, right? It'll quite difficult to get good clear shots.
Not sure, but can try this:
1. Lowest aperture (2.8)
2. Medium exposure (6 - 8 secs)
3. Focus set to infinity
4. Exposure compensation max (+2)
5. Highest ISO - bound to be noisy... use PS to remove the noise
6. MUST use tripod or camera sitting on something that is stable.
I think the problem not so bad if not zoomed to max.
U stay Telok Blangah? That's Bukom refinery, right?
