Star Trails.

[Lensmeister]

Ok now I have seen a number of really cool images of star trains taken on clear nights. I just need to know a couple of things.


What ISO should I use?
What apature?
What shutter (Bulb probably)?
Any other helpful tips ?

Thanks guys :)

Hi Neil, I googled 'photographing star trails' and found a couple interesting sites that might give you some information.

http://www.olegnovikov.com/technical/startrails/startrails.shtml

and

http://www.danheller.com/star-trails

Seems pretty straight forward. I scrolled down some in the second link and Heller had some good things to say about composition and combining techniques.

Thanks for those. Just waiting for the next really clear night down here in Croydon.
