Astro Photography Tips
Just after a collection of thoughts on how you shoot the night sky. I have recently bought a 12mm Samyang f/2.0 lens which I am keen to try on a clear night when the milky way is overhead etc.
I have done a few shots before of stars in general, with mixed results.
What are your tips when shooting the night sky?
I am aware of the 500 rule - 12mm/500 = 24 seconds for shutter time as a rough guide to avoid star trails etc.
I found that having the aperture at 2.0 and focusing on the brightest star with focus magnifier and leaving it open for 20+ seconds with ISO of anything over 1000.... it basically looks like daytime! Would I be better dialing the ISO down to 200/300 and, or shortening the shutter time... its a bit of a puzzle.
How bright do you guys generally want your scene before you go to post processing?
