Hi, I have read bits and pieces in this forum before, but never really seen a thread to discuss about this: how to take star trail photographs?
Granted, there aren't much places to do that in Singapore. I am asking because I might get a chance when travelling. Anyone with recommended readings, please point me to them. Or if you are somewhat of an expert, do share your knowledge on the techniques.
[note] i am more interested in technique. i.e. how to estimate exposure and settings, what to take note of, what pitfalls to avoid. I am not into very serious Astro-photography (take pictures of Saturn or Mars, etc.).
Thanks in advance for viewing and contribution.
