Amita... I think the 1000 with the 28mm will give you good results. "As long as possible" may not give you quite what you're looking for. The lengths of the trails are directly proportional to the amount of time the shutter spends open, and (IMO) the more dramatic trails tend to be shorter, ie less than 1 hour. Also, the longer the film is exposed can lead to more significant light pollution and lower contrast. It's really something you've got to play with. Here's a few that I've taken:
<http://www.sherb.org/albums/startrails/index.html> I have yet to get nice crisp trails; I think the problem is partly the acutance of the film, but very slight vibrations, lengthy shutter times, and condensation may be affecting my results. Here are some other examples that are far better than what I've come up with: <http://www.astrophoto.vze.com/astro/trazos.html> Also, adding something to the frame other than just star trails will help build interest in the image. t On 11/7/04 19:18, Amita Guha wrote: > As I mentioned before, I'm hoping to get some star trails this week, and I > want to make sure I'm not forgetting anything.
